Hi,
I've starting learning this week how to work with Ansys Workbench and have been following a few tutorials.

I've imported an assembly from CATIA made by 2 parts. These were made as solids in CATIA.

I've imported them, created the enclosure but when performing the boolean operation to get the fluid domain and I get an error (red circle with white question mark)

Any ideas?

Further to my previous post. I've isolated the problem to one of the geometries. Doing the boolean operation with the fluid volume - body it works fine. It's only when I try to subtract the wing (attached image) from the fluid volume.

Any ideas?

It was designed as a solid. And should be a solid, unless during the import it changed something. But I imported 2 geometries in the assembly (both solids) and the other one (not shown) is fine.

Error: Boolean Operation Failed
Context: Geometry Engine, while generating Feature Boolean1

In the meantime I'll recheck the geometry in catia to see if I missed anything.

It has been designed a while ago and has been in the wind tunnel for 2 years, I simply just cleaned the geometry in catia last night. it's easier for me to do it there than in modeler!

So here's an interesting one...if I create the flow volume using Primitives - Box, the boolean operation works perfectly. It's just the enclosure that doesn't work.

Any ideas?

I am also getting this error. Can you guys help me. I am doing the boolean operation for surface. I have attached screenshot of my geometry.

In this one part is imported as .igs & added as Frozen operation. The other part is constructed over this part in Designmodeler itself.

It would great if you guys help me.

Thanks

hi rushabh
u must convert surfaces to solid.
