Hi, We have been using PETSc’s block version of the AIJ matrix format to implement fully coupled multiphysics problems using finite elements.
Are there specific advantages to moving toward DMPlex for finite element-based coupled multi-physics implementation? Can you still access Hypre? Does the format support running on GPUs? Thank you. Kind regards, Karthik. -- Karthik Chockalingam, Ph.D. Senior Research Software Engineer High Performance Systems Engineering Group Hartree Centre | Science and Technology Facilities Council karthikeyan.chockalin...@stfc.ac.uk<mailto:karthikeyan.chockalin...@stfc.ac.uk> [signature_3970890138]
