[petsc-users] Inquiry about PetscDS for discretization of second order system

2025-01-03 Thread Gong Yujie
Dear PETSc developer group, I'd like to inquire that if PetscDSSetResidual can be used for second order system? Are there a DS function that is related to solve a system that contains second order time derivative such as time dependent linear elasticity problem. I found there is tutorial for el
