Here i watched a video from "Altair How to" youtube challenge, it says  you can combine a lattice from Implicit modeling and a "B-rep" which creates a triangular mesh then do structural analysis, i can't figure how you apply loads and supports of the mesh, can anyone explain more on this? I've posted the link below

    To run analysis on triangular mesh parts you need to choose the SimSolid solver.  That is under File/Preferences/Inspire/RunOptions.

    To control the faces generated during the conversion to triangle mesh you can adjust the break angle under File/Preferences/Inspire/Modeling Space /Discrete Modeling.

    You can see in this example the break angle was reduced to avoid merging the fillets and flat faces.

    Thank you very much for your help @David Roccaforte, i learned some advanced stuff in a short space of time.
