  1. Problem solved. There where some issue with the node numbers in my model. For MSD the node IDs must be from 1-n without gaps. I thought that they were... but after renumbering the import worked
  2. Hi everyone, I created an external unit cell, meshed it in Hypermesh and defined everything according to the Multiscale Designer Manual - Periodic mesh on opposing faces of unit cell - 3D mesh with only CTETRA elements - One component for each micro-phase (with component ID 1 & 2) - One property (PSOLID) for each micro-phase (with property ID 1 & 2) When I try to import my .fem-file in MSD I get the erroro message depicted below. I tried to import the external unit cell from the examples folder of Multiscale Designer and that worked. So the setup of my MSD works in principal but cannot import my file. Does anyone know how to resolve this? Thanks for your support.
  3. Hi Rahul, I know in principle how to define material orientation for shell elements and did it exactly like in the video, but E1 is always in element XY-plane (as Jan confirmed in the other reply), which is not what i want. I will find another way to achieve the task. Thanks for your reply.
  4. Hi everyone, I need MAT8 material behavior (especially E1 & E2 important) for a curved shell structure, meshed with 2D elements. In my special case, the material orientation (E1) has to be the direction of the Z-axis of the global coordinate system. 2D > composites > material orientation > by system axis > local 3-axis If I define it like that and display the material orientation for the elements, however, the vectors always lie within the element plane and are not parallel to the global Z-axis. Is it possible to have a fixed material orientation independent of element orientation (e.g. global Z-axis) for 2D elements? This would mean that the E1 direction would be out of element plane in some cases, as shown by the orange arrows in the figure below. The pink vectors in the example image always lie within the element plane - thats not what I want. Thanks for your input!
