Issue with running step-55

[Md Mahmudul Islam]

Dear all,

I hope this email finds everyone in this group in good health. Currently, I am working on my code using Step-55, parallelizing it. In my macOS, in deal.IIConfig.CMake, I have made sure to 

set (DEAL_II_WITH_P4EST ON)

set (DEAL_II_WITH_PETSC ON)

set (DEAL_II_PETSC_WITH_COMPLEX OFF)

set (DEAL_II_WITH_TRILINOS ON)

Now I can compile my step-55, but when I run the code, it gives me an error for p4est/petsc/trilinos.

Could anyone please let me know what the issue might be?

Can I run MPI code in my installed dealii, or do I need to delete and start from scratch?

With best regards,

Hello,

You are not supposed to modify configuration files. You need to reconfigure and reinstall deal.II from scratch.

Best,

Bruno

Thank you all. Okay, I will remove Dealii from my laptop and reinstall it. When I reinstall, what should I focus on to run step 55, the parallel code?

You need to configure deal.II with MPI, P4est, and either Trilinos or PETSc with complex support.
