I would like to perform a simulation on a stl file imported on Solidworks. To import the STL file, I open the STL file and I choose solid body in the options. When the file is on Solidworks, I click on "diagnostic of import" to check my mesh and they tell me that the geometry is ok (no intersected faces, ...). But when I want to perform a simulation, it is not possible, I cannot click on the buttons (they are not activated).
Maybe I make something bad in my importation?
Thanks to people who will be able to help me!
