Re: [petsc-users] Construct Matrix based on row and column values

Dear Jed, Thanks I will try to keep you updated. So I managed to get my stuff running with one process but it fails with more than one. The matrix assembly as you described it works fine but I forgot that in the FCT algorithm one also needs to assemble a matrix D that looks kinda like D_ij

Re: [petsc-users] Petsc not work in Windows-10

Hi Satish, The ex2.exe works with "mpiexec -np 2" when I ran it from command line. Then I ran "which mpiexec", it actually points to Intel-MPI instead of MPICH2, probably because I have set the former's path in environment variable PATH in Win-10. I will try to reinstall Intel-MPI and build

[petsc-users] AIJ vs BAIJ when using ILU factorization

Hi All, There is a system of equations arising from the discretization of 3D incompressible Navier-Stoke equations using a finite element method. 4 unknowns are placed on each mesh point, and then there is a 4x4 saddle point block on each mesh vertex. I was thinking to solve the linear equations

Re: [petsc-users] Petsc not work in Windows-10

MPICH is unsupported - and we haven't tested with it for a long time. And petsc-3.4.2 is from 2013 - and untested with current gen os/compilers/libraries. Can you send logs from Petsc-3.12.4 build [or try latest Petsc-3.13.0]? We recommend 64bit MSMPI for windows. Satish On Mon, 30 Mar 2020,

[petsc-users] Petsc not work in Windows-10

Hello, I am trying to build Petsc-3.4.2 in my Windows-10 workstation using Cygwin, with Intel-2018 compilers and MKL, and MPICH2. The configuration/compilation/installation seem to finish without problem, but test program (ex19) failed since it could not find a shared lib. Then I linked the

[petsc-users] duplicate PETSC options

When PETSc reads in a list of options (like PetscOptionsGetReal, etc), we have noticed that if there are duplicate entries, that PETSc takes the last one entered as the option to use. This can happen if the user didn’t notice there were two lines with the same options name (but different values

Re: [petsc-users] Question about DMPLEX/P4EST with different Sections

Dear Matt, I am still not having success with the different sections on the DMForest. The example you sent works only if the two sections are the same. But, if the first section stores the data at the cell centers and the second section stores the data at the cell faces, the code crashes.
