Hi


I am trying to perform the external solar load tutorial in the Openfoam. I am getting the following error while running the "chtMultiRegionFoam" command.

I am just running the tutorial file. I didn't do any changes. Kindly help me to solve the issue.

Perhaps you need to run blockMesh first?

[Yann]

When it comes to multi region solvers, there are several important steps to do in order to generate the meshes and setup the case before running the solver. (blockMesh will not be enough)

Check the Allrun scripts in the tutorial to understand what's done so you can reproduce it.
(Or simply run the Allrun or Allrun-parallel script if you just want to get it done)


Cheers,
Yann

Ok. Thanks. It worked
