Error: Unable to solve linear system using PETSc Krylov solver

Hello everyone,

I am trying to run a script on a computer at my university after correctly activating the fenics module. The output I get is as follows:

nohup: ignoring input
Solving linear variational problem.
Evolution of the tumor up to the third cycle of chemo
Computing nutrient initial condition.
Solving CH + nutrient
Traceback (most recent call last):
  File "GBM_Besta_33_mox.py", line 409, in <module>
    solver.solve(problem, solution1.vector())

While compiling that script on my computer I get a correct execution with an iterative process that I expect.

What could be the problem?

This is almost impossible to diagnose without a MWE or complete information about your builds on your computer and your institution’s facility. A quick check would be whether the underlying versions of FEniCS’s components and PETSc are exactly the same on both machines.
