Cannot find patchField entry for walls

Hello! In my quest to alter the propeller pimpleDyMFoam tutorial to become a helicopter with rotating rotors, I've decided to alter each .obj file a step at a time to figure out why my mesh creations aren't working (I have another thread asking in particular why I can't see my results from snappyHexMesh in paraFoam). Since I am extremely new to OpenFoam (only been using it about 2 weeks now), I have some questions and a bug I'm seeing that I hope some of you more experienced people can help me with:
- Where does the mesh generated from blockMesh go in the vanilla propeller tutorial? It seems to not exist, as the largest mesh is outerCylinder. - If I change the scaling in the blockMeshDict (in either direction - I've tried multiplying the vertices by 0.1, 10, 100, etc.), I get a "Cannot find patchField entry for walls" error in snappyHexMesh. - If I try to use my alternate, helicopter-sized outerCylinder .obj file (attached if anyone is interested in trying this), snappyHexMesh completes successfully but paraFoam crashes and gives me a "Cannot find patchField entry for walls" error. I'm a little confused as to where these errors are coming from, mostly because I don't exactly understand how blockMesh and snappyHexMesh interact. Any help would be appreciated, thanks! |
