Thanks to you! @jousefm @ggiraldo
Yes, I am defining the calculation of the reactions in Simsclae before the simulation. The picture from paraview is the “reaction force” representation.
So, If I understand correctly, the way I should do this is by creating in the CAD model some point in the center of the support face, and then assign the boundary conditions to those “points” (which will be treated as faces I guess, as simscale only lets you assign faces in the Simulation Designer)
