Good day forum.

I'm making a static FEA analysis on Solidworks 2019. I want to create a boundary condition on a surface (it is not a plane, sphere or cylinder) where translations normal to that surface are blocked (set to 0mm).

I've tried using the advanced fixture, but i didn't found a setting that would let me do what i want.

I can apply a force with a direction normal to a face, but i can't find a way to do it for boundary conditions

I hope you guys can help me, i would appreciate.​​​​​​​
