It got soooo much easier with 2.1.x. Just tried the new version of extrudeMesh and if you specify "constructFrom patch;" then the utility sorts out all the boundary patches for you. Here is an...

Oops my bad! Just checked our execution scripts and it is implemented with the -parallel option.

It's up to you. All I can tell you is that -parallel is not needed and it's been a while that you don't have to reconstruct your case anymore. Used to be like that with the older parallel...

By the way you don't have to reconstruct your parallel case anymore. Just process it as you would a serial run. That part of the user guide is outdated.

Definitely skip the -parallel option. It...

That's how I run all my OF executables in parallel for OpenMPI. Use it and you'll see that it works. I just tried the -parallel option and it failed like it did for you. They provide this option in...

Ran it in parallel and snappyHexMesh finishes similarly to the serial run. The mesh also fails two checkMesh tests in both serial and parallel.

I ran it serial and it went okay except for some weird faces in your borde_ataqe and borde_salida regions. The ones in the jpg are for the trailing edge on the Front plane. There area few others. I...

Sounds like a boundary mismatch. Anyway, post it when you have a chance.

It sounds like your dict file is not properly set up. Can you post your case as a tar.gz attachment?

Interesting problem. Are the oscillations self-induced or operator driven?

My work is on snow, ice and rain simulations using two-fluid formulations. I've done some work in aircraft icing as well.

You're quite welcome Daniel. I've been promising myself to formalize this for a while now so thanks for providing a little nudge. This is all going towards creating a wiki page.

creating a 2D mesh with snappyHexMesh

Hi Daniel,

I finally got to spend some time on this and figured out how to do it using only OpenFoam tools. The procedure outline is the following but does not require splitMesh:

Hi Dan,

The extrude/cut process involves using extrudeMesh (which doesn't cut) first and then splitMesh (which cuts) to make the internal boundary external. splitMesh is a bit tricky to use. Will...

actually come to think of it you could keep the original sHM mesh with more than 1 cell in the z-dir, extrude one of the empty faces exactly one cell in the z-direction, select that set of the mesh...

Just set the z-coordinate to one value everywhere. I just took a look at the extrudeMesh tool and it seems to allow specification of individual patches so you might not run into problems there. Of...

Hi Daniel,

I tried once to make a 2D mesh with sHM but got more than one cell in the z direction. I think this is due to the fact that sHM divides whatever you have initially in blockMesh in the z...

Hi Ivan,

It looks like there is a problem with your stl file. The surface cylinder is not closed. Also your refinement boxes seem messed up. If you're doing 2D they should be like this:
