NX NASTRAN ADVANCED FLOW can analyse a domain in motion ?

[Richard1977]

Hello, I have a question. Is it possible that NX NASTRAN ADVANCED FLOW can analyse a domain in motion ?, for example, I need to make an analyse of the flow through a gate valve moving towards its open or close position.

Regards.

R.P.S.

Hello!,
Well, first at all let me tell you that "NX NASTRAN Advanced Fow" don't exist, NX NASTRAN code don't support fluid flow analysis, you are confused with "NX/Flow & NX Advanced Flow" or also FEMAP/Flow & FEMAP/Advanced Flow products from SIEMENS PLM Software that both includes the CFD solver from MAYA Heat Transfer Technologies Ltd (

http://www.mayahtt.com/)

integrated in both NX Advanced Simulation and FEMAP.

After this simply clarification, I can tell you that the MAYA-TMG solver do not support (yet!!, but I guess it will be very soon) moving meshes, it allows to study High speed flow in rotating equipment, support multiple parts rotating with respect to each other, Multi-species fluid mixing, etc..

Yes, you can take account rotation and translation motion influencing the fluid flow, but this is a boundary condition, not possible to perform a "transient" fluid flow analysis remeshing mesh domain as valve moves its open or close position.

Best regards,
Blas.
