Hi Kai,

do you get the same error if you try to run the simulation locally on your computer, using e.g. only two cores?

Hello,

when trying to run a parallel  simulation on a cluster by using mpirun, I get the following error message: Dune reported error: Dune::IOError [VectorP0VTKFunction:/temp/kaiw/DUMUX/dumux/dumux/io/vtkfunction.hh:99]: VectorP0VTKFunction: size mismatch between field process rank (32160) and mapper (17952) ---> Abort!

I tried also to actualize all versions, but the problem remains.
I did the following commands:

srun -n 6 --pty /bin/bash
srun mpirun -n 6  REMEDIATION_3D_cake

Greetings
Kai Wendel
