  1. Hello community, I have a question concerning to apply loads and constraints on 3D surfaces. I have created a solid model from a 2D surface. If I do a 3D multi solid mesh and apply the constraints and the pressure onto the two surfaces (see figure 1), I will get a result. And I can see that every node on the surface is constrained and all elements on the surface are applied with a pressure force. If I create a 2D mesh first and drag the elements along the thickness of the model for a 3D mesh and then apply the constraints and pressure onto the surfaces, I will get no results. And further I can see that not all nodes on the surface are constrained and not all elements on the top surface are applied with a pressure force although I have selected the two surfaces (see figure 2). Why can't I apply the constraints and pressure on surfaces if I create a 3D mesh from a 2D mesh? And why is it possible if I mesh the model with the multi solid subpanel? Thanks in advance.
  2. Hi, I try to make a core shift simulation (multiple bodies) in Moldflow with boundary layers. I used the boolean operation to find the common faces and meshed them after this. The nodes look good, I do not see any intersection or failure, but in Moldflow I always get an error: ** ERROR 304717 ** A node has been found which belongs to both a part element and another element which is not in the part. This is not supported. Please check the mesh connectivity and the element property types. Does anybody know, how can I fix this? Regards, Béla
