I am trying to run a tutorial from openfoam.com. I cannot figure out why my pimpleFoam command will not work when attempting to run the tutorial.

The blockMesh works. Here is the website i successfully downloaded the tutorial from: https://develop.openfoam.com/Develop...dCube/fullCase

Here is the error I am receiving:

I am trying for finsish a class project and would greatly appreciate anyone's help. I also checked the pimplefoam wiki page and can still not find the solution to my problem.

The residual "error" is just a warning that pops up if you do not use residual control (to exit the pimple loop). There is something else that causes the crash.

What else could possibly be causing this crash? Here is my fvSolution file:

I do not know; I've never run that case, but the fvSolution looks fine from first glance. Are you using the same version of openfoam for which the tutorial was designed?

Caelan

I suspect you are not using the "Allrun" scripts to run the tutorial case. The Allrun script setups additional boundary data which is necessary to run the case. If this is not setup, i.e. one runs blockMesh then pimpleFoam, then the error you have provided emerges.

In summary: run using the provided Allrun script.

P.S. I ran using OF v1912, the same version as yourself (according to your build data).
