! subroutine to implement the boundary conditions.
! Here the user should define if the dof is fixed by setting
! kfix((inode-1)*3+idof) to 1 (node inode and dof idof)
! and setting the corresponding value of u, v, or w to the set fixed value
! Same operation for kfixt and temp but for a single dof
! vo is the structure that contains the void information
