This file is read by two subroutines in the code:
- read_controlling_parameters
- read_input_file
The indications between [] indicate the type of the read parameter. It can be
an integer [int], a real*8 [dp], a character chain [char] or a boolean [bool].
CONTROLLING PARAMETERS
_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-
[int]debug is a parameter that switches on/off various prints and outputs
(the level of printing for error, warning and messages of the solver id%cntl(4)
is set to the debug value).
if debug is zero, no debugging
if debug is equal to one, this triggers the terminal display of some key parameters
if debug is equal to two, same as debug equal to one, and the code produces various
vtk files in the DEBUG subdirectories (surfaces, olsf, ...), as well as cross sections
for all nonlinear iterations. Careful, memory consuming !
debug = 1
[bool]doDoRuRe is a flag that triggers the production of output files needed to produce
the DoRuRes. DoRuRe stands for 'Douar Run Report'.
doDoRuRe = F
[bool]compute_qp_gram triggers the production of qpgrams for every grid.
compute_qpgram = F
[bool]compute_reaction_forces toggles on/off the reaction forces computations.
compute_reaction_forces = F
RESTART
_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-
[int]irestart is a restart flag; if irestart is not 0, the run will restart from
an output file given by [char]restartfile and at step.
irestart = 0
restartfile=OUT/time_0187.bin
TIMESTEPPING
_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-
[dp]dt is the time step length (if dt is negative, courant conidition is used and
automatic time stepping is turned on)
dt=1.d-3
[int]nstep is the number of time steps
nstep = 200
[dp]courant is only used when dt is negative; it determines the size of the time
step from the maximum value of the velocity field amplitude. The time step s
the product of courant by the ratio of the smallest leaf size by the maximum
velocity.
courant=.5d0
[bool]normaladvect is a flag used to determine which algorithm to use to calculate
the new geoletry of the normals to the surfaces at the nodes on the surfaces
if normaladvect is T, the normals are advected using the velocity gradient
if normaladvect is F, the normals are re-computed from the geometry of the
surface
normaladvect = T
GRID ITERATIONS
_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-
[int]griditer is a flag that allows for nonlinear iterations; when positive, a fixed number
(griditer) of iterations is permitted; when negative, the number of
nonlinear iterations is determined by a convergence criterion.
griditer = 1
[dp]octree_refine_ratio is the threshold value used to determine whether the octree
has converged or not. the larger the value, the less stringent the test.
octree_refine_ratio=1.025d0
NONLINEAR ITERATIONS
_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-
[int]nonlinear_iterations is the maximum number of nonlinear iterations (i.e. the
iterations on a given constant grid)
if nonlinear_iterations is positive, it simply is the number of nonlinear
iterations performed for each grid. When negative it indicates an upper bound
of nonlinear iterations, but the actual number of nonlinear iterations is
determined by a convergence criterion (see the 'tol' parameter)
nonlinear_iterations = 1
[dp]tol is the relative tolerance used to estimate convergence on the computed
velocity field
tol=0.01d0
[bool]adaptive_tol is a flag that toggles on/off the evolution of the tol parameter
with the grid level: when velocity convergence is reached on a grid, the
latest meaure of the velocity difference between the two last obtained
solutions is put in tol, so that on the following generated grid, the solution
reaches at least the same level of convergence. It allows to start with a not
too stringent value of tol at uniform octree level that evolves with every
grid, assuming that increasing the level of refinement of the octree allows to
better capture the solution, hence allowing a tighter convergence.
adaptive_tol = F
OCTREES
_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-
[int]leveluniform_oct is the level of uniform discretization of space; note that a
level is a power of two used to divide the unit cube
leveluniform_oct = 5
[int]levelmax_oct is maximum level of octree discretization
levelmax_oct = 6
[bool]ismooth is a flag to impose an additional level of smoothing after refinement
for the surfaces and strain rate. It ensures that no leaf is flanked by
other leaves differing by more than 1 level of refinement
ismooth = F
[int]noctreemax is the maximum size of any octree used in all computations
noctreemax=10000000
[dp]refine_ratio is used to determine octree refinement based on a given criterion.
All leaves where the criterion is larger than refine_ratio times the maximum
of this criterion are refined
refine_ratio=-10000
[int]refine_criterion determines which refinement algorithm is to be used.
Several criteria exist for the refinement of the osolve octree. 1 is the second
invariant of the deviatoric strain-rate tensor; 2 is the sum of the squares of the
diagonal terms of the deviatoric strain-rate tensor; 3 is the second invariant
of the deviatoric strain rate tensor timses the leaf size. any other value sets
the criterion to zero and leads to no refinement.
refine_criterion=1
[int]initial_refine_level is the initial level at which the refinement of the
octree will be performed. it has to be smaller than levelmax_oct
this should be used (different from levelmax_oct) in case the flow is very
localized (nonlinear/plastic analysis)
initial_refine_level = 5
[bool]renumber_nodes is a flag that can toggle on/off the renumbering of the nodes
by mean of Sloan's algorithm (T/F)
renumber_nodes = T

[int]smoothing_type is a parameter allows to choose which type of smoothing is to
be applied to the pressure field: 0 is none, 1 is center->nodes->center, 2 is the
same, but weighted by neighbouring elemental volumes, 3 is regular grid+SPH, and 4 is SPH.

[int]levelcut is the number of levels used to estimate the volume integrals in the
divFEM algorithmi for cut cells; by testing, it has been estimated that a value
of 2 is very accurate
levelcut=2
[int]levelapprox is the number of levels used to estimate the remaining integrals
using an improved version of Marthijn's clever algorithm, usually 3 is plenty
levelapprox=3

[int]nmat is number of materials
nmat=1
[int]material0 determines what is the material above the 1st surface (the free
surface) if material0 is 0 then it is the void and the properties "0" are used
for that part of the model; otherwise the material is one of the material,
comprised between 1 and nmat
material0 = 0
[dp]densityi, [dp]viscosityi and [dp]penaltyi are the density, viscosity and
incompressibility used for material i; there should be nmat sets of material

SURFACES
_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-
[int]ns is number of surfaces to track
ns=1
for each surface, one needs to define a levelt, itype, material, surface_type, activation_time
and surface_params .
- [int]levelt is the inital level for the particles on the surface; to be accurate
and avoid wholes in the surface during definition of the lsf, one should use
levelt eq to levelmax_oct+1 for all surfaces as a minimum value;
- [int]itype should be 1 for foldable surfaces or 0 for nonfoldable surfaces;
- [int]material is the material type refering to the table of material available (max nmat);
- [dp]activation_time is the time the surface becomes active (before that time, it
is glued to the 0th surface). this parameter is useful when defining stratigraphic horizons;
default is -1, ie the surface is not glued to the free surface
- [int]surface_type is comprised between 1 and 8.
1 corresponds to a flat surface,
-> surface_param_01 is the z level
2 to a rectangular emboss,
-> surface_param_01 is the z level

[int]niter_move is the number of iterations used to update particle positions
using an implicit, mid-point algorithm (default is 10)
niter_move = 10
[dp]stretch is the maximum allowed increase in linear length between two initially
adjacent particles on any surface; when this stretch is achieved, a new
particle is inserted on the surface, half-way along the stretched edge
stretch = 1.5d0
[dp]anglemax is the maximum allowed angle between two adjacent normals
when the angle is reached a new point is inserted beteen the two points to
reduce the angle between the two normals
anglemax=180.d0
[int]criterion is criterion used to define the octree in the vicinity of the
sufaces; criterion 1 corresponds to imposing that all leaves that are cut by any of the
surfaces must be at level levelmax_oct; criterion 2 corresponds
to imposing that discretization is proportional to the curvature of the
surface; curvature is calculated from the local divergence of the normals.
criterion 3 corresponds to imposing that all leaves that contain at
least one particle of any surface is at levelmax_oct;
criterion = 2
[dp]anglemaxoctree is only defined for criterion 2; t is the maximum allowable angle
between two adjacent normals; if the angle is greater than anglemaxoctree, the local
octree leaves are forced to be at level levelmax_oct; otherwise they are
proportionally larger (smaller levels) (default is 10)
anglemaxoctree = 10.d0
REFINEMENT IN BOXES

[int]nboxes is the number of boxes in which the user imposes a set level of
discretization
nboxes = 0
for each box we need to specify the two end corners and the level
the syntax is [dp]boxnx0, [dp]boxnx1, [dp]boxny0, [dp]boxny1, [dp]boxnz0, [dp]boxnz1
and boxnlevel where n is the box number

_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-
[bool]ref_on_faces toggles on/off the user imposed refinement on faces.
for each of the six faces of the cube, on defines the level at which the
desired area is to be refined. this area is given by bottom, top, left and
right coordinates that are comprised between 0 and 1
faces 1,2,3,4,5,6 respectively correspond to x=0,x=1,y=0,y=1,z=0,z=1

EROSION
_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-
[bool]erosion is a flag that toggles on/off the erosion.
erosion = T
if erosion is on, one also needs to set the erosion level/height, [dp]zerosion
Note that this is a first attempt at erosion; in future versions, DOUAR
should be easily linked to a surface processes model like CASCADE
zerosion=.1d0
If erosion is on, one also needs to define a length scale and a velocity scale to
properly translate the uplift rate produced by DOUAR into something that is adequate
for CASCADE;
[dp]length_scale is the scale of the unit model in km
[dp]velocity_scale is the velocity scale in km/Myr.
if length_scale is negative, erosion is assumed to be perfect (no call to CASCADE is needed)
length_scale=200.d0
velocity_scale=10.d0
One then needs to define the erosion constants in CASCADE
[dp]fluvial_erosion is the fluvial erosion constant in 1/m^2
[dp]diffusion_erosion is the diffusion erosion constant in m^2/yr
(4d-2 32d-2)
fluvial_erosion=2.d-2
diffusion_erosion=16.d-2
One finally needs to specify the boundary conditions for CASCADE
if [int]baselevelx0 is set to 1 then the boundary at x=0 is set at baselevel (water and sediment exit)
if [int]baselevelx1 is set to 1 then the boundary at x=1 is set at baselevel (water and sediment exit)
if [int]baselevely0 is set to 1 then the boundary at y=0 is set at baselevel (water and sediment exit)
if [int]baselevely1 is set to 1 then the boundary at y=1 is set at baselevel (water and sediment exit)
baselevelx0=1
baselevelx1=1
baselevely0=0
baselevely1=0

[int]nsections is the number of cross-sections to be output. [dp]scale is the scale used to produce the postscript file.
[int]xyz takes values 1, 2 or 3, and corresponds to planes defined by x=constant, y=constant, and z=constant resp.
The [bool]flags are self explanatory. [char]colormap is the chosen colormap (jet or hot). [int]ncolours is the number of
colours used to produce the plot.
