Dear all, I need to set a pressure reference point in my parallel FSI code by modifying the matrix, and I realise the following PETSc function may allow me to do this: MatDiagonalSet (…) Has this been implemented in FreeFEM (seems I cannot directly call it in my FreeFEM code)? More generally, wh…

Call PETSc matrix operator MatDiagonalSet (…)
