Hello everyone,
I hope this email finds you well.
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.
