Para solid model

Recommended Posts

Dear sir,


 I am importing para solid files into Acu solve but to run acu solve simulation the parasolid should be of solid type but what i am using is a hollow cylinder to analyze the fluid flow at one inlet and two outlets, similar like Y channel. my query is how i can i make my hollow cylinder of para solid type to analyze in Acu solve.Will it be possible to do my simulation. if not what steps i have to take???

Thank you !!!
After following the tutorial I did the same steps to my model and I tried to export as parasolid again from hypermesh so that i can import in acusolve for solving. but to my surprise I found this error.. Can you please tell what is this error and how can i debug this !!!

It might  probably be helpful to visit HyperMesh training. That would be helpful to get you started with HyperMesh basics requried for such tasks.


 


For the current task, you could also use SolidThinking Inspire 2014 to get the negative/fluid volume from the hollow part. Use the "plug" option to get the fluid contact area.

In your CAD package, if you have the true solids defined - but you want the fluid volume for CFD - you can add the inlet and outlet(s) faces as simply surfaces, then export the ParaSolid.  In this case, the solid volume in the CAD is representing the solid material - and the fluid material is represented by 'void' but bounded by surfaces.  When you import the parasolid to AcuConsole, enable the option to 'Fill Voids' and the 'solid' for the fluid volume will be cretaed during the import process, based on the bounding surfaces.


 


In AcuConsole, place the 'solid' region into a separate Volume group, and set the Volume Mesh Attributes to 'No Mesh' for that group.  That volume and its attached surfaces will not be meshed.


 


Work with the fluid volume and its bounding surfaces as normal.
