Dear Petsc-User,
Hi, I am Seungjin Seo, and I am trying to use PETSC to solve my problem.
I want to solve a heat conduction equation using finite volume methods in 2D
and 3D.
I am going to import Gmsh files. Can you recommend me an example case for this
purpose?
Also, can I set different

Hi Valentin,
Have you seen this example:
https://bitbucket.org/petsc/petsc/src/1830d94e4628b31f970259df1d58bc250c9af32a/src/ksp/ksp/examples/tutorials/ex2f.F?at=master=file-view-default
Would that be enough to get started?
Thanks,

Hello!
My name is Valentin Egorov. I am from Russia. And I have a question for you
about PETSC. I would like to make a programm on Fortran with PETSC, but I
can't. I have a matrix 400*400. I have also vector B with 400 elements. I
need to solve linear equations. Could you help me to do it. I can't

How about the attached patch for getting PETSc built for complex

I like it and now I notice that PETSC_CLANGUAGE_CXX now appears in only
one place (CHKERRCXX), which I hope we can also

Hi Barry, Matt, and Satish,
Thank you for the quick responses. It's true I forgot the return 0 at the
end. I remember I was looking at it before and meant to add the line in but
I sent the original version of the code.
I had a working version of the mpi compilers on my computer but I
understand

The can also run with valgrind

Hello Randall,
As far as I know, if you don't set particular device the device with
index 0 in cuda device array will be used (at least tried to be).
Otherwise, you can use cudaSetDevice or cudaChooseDevice
