I've got cell A with geometry of a fin, and cell B with geometry of a box. I would like to merge these two geometries in cell C for further meshing for CFD simulation. Just linking A to C works but then B and C don't link.

Hi,

Please refer to the following discussion, it may answer your question: Merging geometry from two different models (ansys.com)

Thanks

Hi Deepak. It could work, but not for me, I don’t need a Mechanical model. I tried anyway and there is another issue: it imports the geometry into new geometry without me being able to edit it. For example I could import the fin and duplicate it, to have two fins in my box. I end up having only access to edit mesh in cell C but not the Geometry.

 

 

Then in the mesh in cell C I select the box and try to add 'inflation' method for box with boundary at fin, and it remains deselected, so it considers them different parts or something.

To have more control over geometry, create a new geometry file by importing those two geometry, and use that in the final analysis.

Hi Deepak. Sure, I will do this for now. I am worried though that if I change the fin geometry then I'll need to manually export and then import it -- two manual operations (whereas I was expecting that updating fin geometry in cell A would automatically update it in final geometry). Is this correct?

Yes, updating the geometry in Project A, auto-updates the geometry in the combined project.
