Well, From what you've said S, I wish I had STAR at the moment.

You're right that getting info from Fluent Inc is like pulling teeth or getting blood from a stone.

I think that the comments that Fluent Inc. has a good marketing machine are correct. I know the local CFX distributor has done a lot more technically than any of the local Fluent people, who's knowledge of what Fluent does behind the scenes is, well pretty much limited to what the manual says.

For the record, Cances did used to be the distributor but no longer - though my professor's company CFD-Res still is. So while some people around me are tied to Fluent, my connection is not commercial and is only as a user.....A frustrated and discontent user at the moment I might add.

In the moving mesh capability in STAR CD can you write code so that the wall boundaries/mesh moves as a function of solution??? For example in reaction of a solid boundary, the boundary will move at the rate determined by solution of the reaction problem.

How easy is it to do?

Greg

It is possible. You have to collect the flow information in the "posdat.f" and transfer the data required for the mesh movement via COMMON-block to the "newxyz.f" subroutine. There you can move the verticies.

Then it is up to you to define the mesh-movement, which ist much much easier to do for a hex mesh ...

Only now I know the area of interest. It is automotive, in particular: external aerodynamics, underhood air flow and thermal management, heating, ventilation and air conditioning.

Could you also suggest me some books or magazines about these problems.

Thanking in advance I remain.

Best Regards Giovanni
