My group is developing an open source finite element library Hermes2D that can do space-time adaptive hp-DG with dynamical meshes for compressible Euler equations. That's about the best you can do.

If you are interested, you can give it a shot. The software can be downloaded from http://hpfem.org/. There is a comprehensive tutorial as well. You would have to be ready to commit enough time to it. We will be able to help but we will not have time to do your work for you.

Hi Dr. Solin,

      I was given your name by Dr. Henry Fu (see below).  I had asked him if he had any familiarity with computational fluid dynamic codes.  

I wanted to model a transient case of gas flow through a supersonic laval-type nozzle.  I wanted to know if you have modeled anything similar?  What CFD codes did you use?  I have looked briefly at the freeware CFD code openFOAM but didn’t want to dive in without getting some advice first.

This effort would be part of experiments at the Nevada Terawatt Facility using gas puffs as the load for the Zebra current generator.  These loads are cylindrically symmetric.  Any help would be awesome.  Thanks and cheers,

Erik McKee

Dear Erik,

I haven't personally used any CFD packages besides COMSOL (and that very sparingly).  We typically write our own codes for numerical calculations, and they are specific to low Reynolds number situations (i.e., a very different regime from what you are interested in). 

So I'm not really sure I can even point you to something appropriate for your case.  You might want to talk to Pavel Solin in the math department who I think may have more direct expertise.

regards

Henry
