Folks, CD-Adapco site mentions that StarCCM+ can handle high speed flow, which was never a strong point of STAR-CD. Has anyone tried this code at high supersonic, low hypersonic speeds. Say Mach 5 to 7?

Just curious - Andy R

Hi Andy - why are you worried about Mach 5 inside a BaRT model?

Cause now I work on cool stuff... Or rather really hot fast stuff. We use GASP and FLUENT Gasp is excellent for high speed flows, thats what it was designed for. So far we seem to get reasonable results with fluent up to mach 5-7, though gasp has better gas phase physics (variable gamma etc).

That said, a lot of our geometries have sharp spiky bits (high speed flows generally do) and block structured meshing is painful, but we have no real confidence on FLUENTs abilty to capture shocks and expansion waves with a tet mesh, and GASP can't run tets(yet).

Poly's look like an interesting option and Mr Jones dulcet tones on the CCM+ demo lulled me into thinking about other options.

Now, TG hmmm......

Remind me not to auto sign my name next time!!
