Geometry finalization - Assembly model -> thermal stress analysis
Hi, I am working on a thermal stress analysis of an assembly in 4.3b and am a bit confused. I thought all the structural mechanics analyses where parts are in overlap should have it's geometry...

Hi Matej, If your geometric entities are not touching then Union and Assembly result in the same model, except that Assembly can automatically create the Contact or Identify Pairs for you. If they are...

Hi Nagi, thanks for the reply. By overlapping you mean when two elements (geometric entities) are in interference, right? Based on the tutorials, it seems you are right for "snap hook penalty" and for...

Hi, When you do a Union, you essentially assume that all (overlapping or contacting) parts are 'welded' or 'glued' together. This means that there is no jump in displacement or temperature at an...

Hi Henrik, Thanks for your reply. if I understand correctly then forming a union is not appropriate for computing models which are assembled from different parts and materials. Let's say we have an...

Hi Matej, For an assembly with an interference fit it is often appropriate to use Union, when studied from the structural mechanics point of view. But if sliding could occur, then an Assembly should be...
