The version on github should work in parallel. What's the problem exactly? It would help if you provided more detail - like a stack-trace or a small test-case that can reproduce the problem.

That's what other forum posts seem to hint at. You might be stuck with a buggy version. You may also want to test out Hrv's branch at 1.6-ext, since he's been making...

That's because your runTime.write() is after your solution loop. Place it after the mesh.update() call, and you'll get the mapped field written out to disk. You'll have to roll-up your sleeves...

You might want to manually print out the velocity field in the newly created cells (and face-fluxes phi for newly created faces) after the mesh-update to ensure that it looks reasonable. Is this...
