SpaceClaim Geometry Combine of Multiple Untouching Solids

shadymody · April 14, 2022, 12:19

Hi,

In Spaceclaim, I am trying to combine solids that are intended to be one domain, but they are not in contact with each other. Like Trees, so each tree is in a separate location, and I want to merge them in SpaceClaim so that I will have only one domain in Fluent and Only one wall interface in the boundary conditions.

I used to create the geometry in Autodesk inventor which allow this feature, and then export STEP and import to Ansys. But now I'm forced to use Spaceclaim because I have imported Geometry from OSM and its the only way I can turn it to soilds in spacecalim. But spaceclaim does not accept to combine solids that are not in contact with each other. Is there any way around?

I hope someone can help.

Thanks

You need to check if they have overlap,
If so, then remove the overlapping regions.
Then you have to go to menu Workbench and use the Share Topology.
If everything goes well, then the mesher will see only 1 surface in between the solids that allows for interface definition in Fluent
