Default StarCD and Gambit issues
Posts: n/a

Further to my previous post, I decided to generate a much more complex mesh in Gambit (hopefully to reduce the overall memory requirements).

I have 2 issues:

1) Importing a *.neu (Gambit neutral file) reads in the mesh fine, but no boundary areas are brought through. This is a real pain as StarCD is pretty rubbish (as far as I can tell) at providing a clear way of setting boundary locations other than pointing and clicking...

2) Importing a *.msh (in a similar process to Fluent) using the "TGRID" command crashes StarCD ("/opt/starcd/PROSTAR/3.24.000/linux_2.4-x86-glibc_2.3.2/bin/prostar: line 243: 10437 Segmentation fault ${PROSTAR}/bin/pro-${PRODR} ${CMAP} ${BATCH} ${ESTOOL} ${RUN_OPTION} ${PROSERV} ")

Does anyone know a way I can bring all the info from Gambit to StarCD, including boundary info?

Or, as an alternative, does anyone know how I can set boundary locations _without_ using the mouse to click on a particular cset? I shall elaborate:

At the minute I can set boundaries using a sequence of commands like this:

cset news gran -0.1 1.1 -1 33 -1 33 cset dele gran -0.1 1.1 6.9 25.1 6.9 25.1 view -1 0 0 cplo vset news edge bfin 2 vx

!click on a vertex

RDEF 2 INLET $ 0.35,0,0,1,0,997.561 RNAME 2 outer

How can I achieve this without having to click?

It may by that combining the import of a *.neu file with commands like these will allow me to circumnavigate the need to bring through the boundary locations from Gambit...

Thanks for any help.

Create new boundaries using options surface based on edges or surfase based on vset Mabe try new version of gamit. On old version i have similar trouble. Or use ICEM CFD it is mach cooler. Or bulid your mesh in prostar (very powerfull).
