Spaceclaim: Error occurred while creating the enclosure (protruding bodies).

[labdulal]

Hello,

I am defining a domain around a canoe to perform a simulation, and I am using only half the canoe because it is symmetrical. When I try to create an enclosure and have the side of the enclosure directly against the canoe (0mm away from the canoe's symmetrical side), I get the following error: "An error occurred while creating the enclosure (protruding bodies). Try increasing the cushion value."  But, when I increase it to for instance 1mm, I am not able to define the canoe's surface as a "Named Selection" in the "Groups" list because it is within the interior of the enclosure. This then prevents me from applying any mesh local sizing in Ansys Fluent.

I would appreciate any help to be able to define the canoe imprint within the enclosure as a separate face/surface.

The following screenshot below is from Ansys Fluent. It shows that the canoe and the enclosure are considered as 1 surface:

Thanks.

1. Start with the whole canoe and make a plane at the center for later use.
2. Create the Enclosure on all sides of the canoe.
3. Use the plane to slice the canoe and Enclosure solids and delete the unwanted half to create the symmetric model.
