Finite Element Analysis Toolbox
BDRDLIP Set slip boundary conditions.
[ A, F, PROB ] = BDRSLIP( A, F, PROB, I_DVAR, J_BDR, SOLVE_STEP ) Sets slip boundary conditions in the global matrix A and right hand side/ load vector F with the information in the finite element problem struct PROB. I_DVAR inidicates dependent variable number (should correspond to x-velocity) and J_BDR the boundary number. SOLVE_STEP indicates if function call is before the linear solver call (=1) or after (=2).
