3D ACMI - moving prism in a fixed box

EJ_Pellegrino · October 16, 2020, 13:23

Hi, I'm trying to set a 3D case starting from the oscillatingInletACMI2D tutorial.
I want to simulate a crosswind on a straight moving prism in a box domain (with the prism longer than the box so that there's always a part of the prism inside).
I encounter this error when I run the createBaffles application:
--> FOAM FATAL ERROR:
Illegal non-overlapping patch name ACMI1_blockage

This sound really strange to me since I just modified the 2D case.

These are the step I follow:
blockMesh (on the first block)
blockMesh (on the second block)
mergeMeshes [folders] -overwrite
topoSet -constant
createBaffles -overwrite
cp -rf 0.orig 0
pimpleFoam

I found out that the error was defining just one patch for the 3 different faces. Even if they are of the same type and will changed in the same manner in topoSet, they must be defined separately.

Hope that this will help someone in future
