CFD in Catia?

[fastline12]

We were looking to do some CFD work with a pump design. A friend's shop runs Catia V5R20 but they were not sure if Catia could do CFD simulation or if we need to get an addon or what? What is the best way to go? Do we need to get a totally different program and import the model into it for testing?

Two main suppliers of integrated CFD for CATIA - Ansys fluent & Star-CD

I take it Dassault does not have this ability yet?

DS don't try to develop every bit of functionalit, as the markets they participate in have there own requirements, like using nastran for certification analysis. They leave specilist tools to those who have the experties in those area, but provide the tools and interfaces for tight integration of those specilist tools into the CATIA shell

There might be something in the Simulia family of products, but it is not likely to ever be put into the CATIA brand as this is the mechanical design product line and not simulation. All (with a few caveats) the DS products lines integrate into the same data stream and interface as this is one of the core ideas in PLM.

Like PeterGuy said, there is a CFD tool in Abaqus, the Simulia brand. But I haven't work with Abaqus so I don't know how it interacts with Catia.

Catia v5 only supply linear analysis.
if you want to slove CDF problem, you have to use Abaqus or ansysWB CFD.
