Hello guys,
I have a turbine I want to simulate and first I need to create the fluid volume.
I started importing my Volumes (walls and Rotor [solids]) the I did boolean operation to substract rotor from walls but it doesnt really work I get this in my model tree, the boolean option has a green arrow but doesn't appear in Parts / Bodies, could you help me?

The green checkmark just means that DesignModeler thinks your fluid operation was sucessively completed. If you are removing the overlapping region of rotor from the walls, there may not be a new body created unless the rotor body intersects the walls in such a way that the wall bodies are no long contiguous (zusämmenhangend). Maybe a couple of picture of your geometry would help.

Hello Wilk,

Yes, as NickFL mentioned the operation seems to be completed, however it is good to check your original model.

Can you provide more details and images if possible?

Once you import your model how many 3d volumes you have? I expect you might have 3 volumes in total, 1 enclosure/turbine, 1 Rotor and 1 MRF region/domain enclosing turbine rotor. so you will be doing Boolean operation to subtract Rotor and MRF region from enclosure and suppress the parts which are not required for your Fluids simulation.

I do not know what are those 4 surface/shell bodies in the model tree, can you explain what are those?

Regards,

Anil
