I ran snappyHexMesh and am now trying to run extrudeMesh. However, extrudeMesh can't seem to find any of my patches. Do I have some sort of syntax error or do I just not understand how extrudeMesh works?

// What to extrude:
//      patch   : from patch of another case ('sourceCase')
//      mesh    : as above but with original case included
//      surface : from externally read surface

//constructFrom mesh;
constructFrom patch;
//constructFrom surface;

// If construct from patch/mesh:
sourceCase ".";
sourcePatches (right);

Output:

Disregard, I was being an idiot.

What were you doing wrong? I have the same issue.

[mrishi]

Never mind, I understand

[dragon boy]

I have the same issue, how to solve it?

Double check that your point in the snappyHexMeshDict is inside the volume generated by the extrudeMesh.That fixed it for mine.

ok thank you!
