Hi All,

I am facing a problem in running tutorial 7.1. When I sent a file to star solver, the solver hang with message - executing promove.bat. I just couldn't figure out what is the error source. FYI, I am running Star CD-v3.15A on Windows NT platform.

Thanks.

This might be your problem - do you have a single license of prostar and star solver? Here's what happened to me. I had prostar open and then went to the starlauncher to solve the problem. But promove.bat will invoke prostar to process the mesh movements. So if you have only license prostar, it will hang.

Get out of interactive prostar then solve the problem.

Hi Jerry,

Thanks for your respond. You are right. there is only a single license of prostar and star in my company. But I have quit Prostar before running Star solve. The program hung just after completing GEOMETRICAL CALCULATIONS. Any clues?

Thanks.

Did you run pmovrun.bat (NT equivalent of pmovlink)? Tutorial 7.1 is a moving mesh problem and requires that you run pmov before star.

Also, check the jobname.echo and jobname.info files for potential errors during run-time. If you ran pmov, then look at pmov.error for any problems.

This is my LAST post on this subject. Does the moving mesh capability work in NT? Yes. Does it work as advertised by Adapco? Not really. Have I successfully run Tutorial 7.1 in NT? Yes.

What kind of problems can you expect?

1. Mesh generation: none. 2. Transient definition: none. 3. Events and grid movement: none. 4. Processing events (pmov): maybe - the UNIX copy commands didn't work, so I had to manually copy parm.inc.new to parm.inc. 5. Run star executable: possibly - any number of things steps can cause star to fail to run (i.e., failing to create the jobname.evnt, not copying the parm.inc). If you don't resize the memory and set maxeve to 100, then you'll get errors when reading in the input file and defining the events. Also, if you don't have enough licenses and leave the Prostar GUI up, it will also hang.

I have talked to Adapco, and I was told that solving via the StarLauncher in NT doesn't always work; instead, open a command prompt and run pmov and star manually.

Moving mesh is not a simple class of problem to solve (UNIX, Linux or NT). If you're learning Star-CD and also trying to pick-up moving mesh at the same time, you're taking on a big task. Learn the basics first.

Jerry,

Thanks for your precious advices. I will try out the steps that you mentioned above and let you know what is the outcome.

Thanks again
