Hello.

I have this simple setup with snappyHexMesh. Snappy fails silently before starting snapping. I'm afraid it might also be a system issue (I work on Windows subsystem for Linux).

These are the few last lines from snappy output:

Checking initial mesh ...

Could someone please run the attached case and see if it works? I have run out of ideas for debugging this one.

Thanks!

I figured it out.
There's nothing wrong with geometry, blockMesh, snappyHexMesh or anything else.

In controlDict there was

deltaT 0;

I have no idea where this number came from but it caused my strange non-error.
