Hello, I don't think that I set preallocation values when I created the matrix, would you please have look at my code. It is just the petsc related part from my code. I was able to fix some of the error messages. Now I have a new set of error messages related to the KSP solver (attached)
I appreciate your help Sawsan ________________________________ From: Mark Adams <mfad...@lbl.gov> Sent: Wednesday, December 20, 2023 6:44 AM To: Shatanawi, Sawsan Muhammad <sawsan.shatan...@wsu.edu> Cc: petsc-users@mcs.anl.gov <petsc-users@mcs.anl.gov> Subject: Re: [petsc-users] Help with Integrating PETSc into Fortran Groundwater Flow Simulation Code [EXTERNAL EMAIL] Did you set preallocation values when you created the matrix?

If this is what you want then you can tell the matrix to let you do that. Otherwise you have a bug.

My Name is Sawsan Shatanawi, and I am currently working on developing a Fortran code for simulating groundwater flow in a 3D system. The code involves solving a nonlinear system, and I have created the matrix to be solved using the PCG solver and Picard iteration. However, when I tried to assign it as a PETSc matrix I started getting a lot of error messages. I am kindly asking if someone can help me, I would be happy to share my code with him/her. Please find the attached file contains a list of errors I have gotten Thank you in advance for your time and assistance. Best regards, Sawsan
