Creo 10 Flow Analysis cannot calculate with more than 3 domains.

[SM_9149671]

In Creo 10 Flow Analysis, when I try to create a mesh for analysis with a model containing 3 or more domains, the meshes for some domains are not generated.
Also, the I/F between domains is not recognized.
In our previous use of Flow Analysis in Creo 7, a mesh was generated for all domains in a model with up to 7 domains and all inter-domain I/Fs were identified.
(We are not aware of the maximum allowable number of domains.)
Using this previous model used in Creo 7 Flow Analysis, or creating another new model, does not work in Creo 10 Flow Analysis.
Note that even in Creo 10's Flow Analysis, mesh generation and inter-domain I/F identification is still possible for up to two domains.
Is there any special way to handle equal or more than 3 domains in Creo 10 Flow Analysis?
thanks

Hi,

please report the problem to PTC Support.

Hi

We don't have any limitation of domain numbers for flow analysis. My guess before testing your model is that the tessellation of creo parametric fails. Flow analysis uses tessellated Creo model when generate the mesh. The failed tessellation leads to missing boundaries/interfaces. Please share this model with us and we can discuss. Thanks

Thank you for your response.
I cannot provide the actual data used for analysis, so I will present a modified version. It will take some time to create that model, but once I have uploaded it, I would appreciate it if you could review it. Thanks.

Sure, no problem. please email me "ls at simerics.com" Thanks.

The analysis seems to work for simple models, and it has taken a long time because I have tried many different models.
I was using version 10.0.3.0 and was able to get comments from others that version 10.0.6.0 solved the problem.
I tried upgrading to version 10.0.6.0 and am now able to analysis.
Thanks.
