, I have to do simulations on a maple seed in autorotation but I encounter some errors related to the creation of domains. Using the enclosure tool, I can't center my domain on the center of gravity and by creating a sketch and then using the extrution tool, the domain is well centered on the center of gravity but it behaves strangely when using the bolean, which creates a lot of errors afterwards.

Do you have by any chance a solution to this problem?

The enclosure doesn't have a way to choose a center point.

You can get the centroid with "Measure > Mass Properties":

I would say creating a sketch about this center and then pulling to a solid is the best method. Before exiting sketch mode, hide the bodies, so that the sketch doesn't imprint on them. When you pull to a solid, select the "no merge" option. Then use the Combine tool to subtract your bodies from the body you just made.

When the enclsure tool works it subtracts the body inside which is the same thing that is done with the Combine tool. If you can't manually subtract your body using the Combine tool, the enclosure tool would have the same problem. Right click on your bodies in the Structure tree and choose "Check Geometry" and fix these before boolean operations can work.

Thank you for your answer,
I am currently using designModeler but it doesn't seem to me that the combiner tool is present in it. Would there be a solution by staying in DesignModeler or is it absolutely necessary to switch to spaceClam to create this domain?
