  1. Hi, I ran a modal analysis of my model and somehow the MODAL EFFECTIVE MASS exceeds the total mass in some cases. I assume that this is not how it should be? Can anyone help please?
  2. Thanks! Any chance that I can export an excel directly or do I find the result in the .out file only?
  3. Hi, How can i extract results from an modal analysis? I want something that looks similiar to this: Right now I can only find the modes in the Output file, but the percentage of mass would be helpful. Thanks in advance.
  4. The shaft grows, it has a rotational dof. It is connected to the middle part with RBE2 and CBUSH which connects the rbe2 spiders, which has a K6 = 0 Stiffness.
  5. Hi, I have a model with certain parts with a free degree of freedom (rotational, actually ball bearings). In the static analysis it happens, that the part "grows", which obviously is wrong, and I believe the reason is that it is not constraint for every dof. How can I fix this and still keep the dof6 unconstrained? Thank you all!
  6. Hi, Can I change QUAD4 Elements to QUAD8? With 2D --> config edit its not working. It states: "Invalid conversion (such as adding nodes to an element)" But I am just changing the input for the solver, aint I? Thanks for your help.
  7. Hi, Thanks for the quick response. This is just a cut out and actually there are kind of "arms" attached to this solid, whose mesh has to be considered. Line Drag or Spin would just create the mesh I believe. Thats why I am trying to fix this instead of creating a simple new mesh. Thanks.
  8. Hi, When I create a SolidMap for one of my Solids it states in the left bottom corner: "Waring: dest has 2 unmatche fixed points. Node associations my be wrong." And the outcome is this: How can I fix this? Thank you.
  9. Hi, I have two CONM2, but they are included. The total mass varies also from what HM calculates. In the .out file it gets to much mass, which means that I did not miss to export some parts. Any further ideas?
  10. Hi everyone, I am wondering why the Mass in my .out file is diffrent from the Mass in my Hypermesh model. It is in tons, so dont wonder why its that low. This is from the .out file: This is the Design Space: And This is the rest: Thanks in Advance.
  11. Hi, I need to calculate the angle between a tracking system and the global system. How could I do that? I did not find a particular function to calculate the angle between a tracking system and a normal system. Thanks in advance
  12. Hi, I do not understand what the Coordinate Systems are for? first grid and second grid are the nodes to connnect with the revolution joint i believe. But how is the axis for the rotational freedom defined and what reason have the GID1 and GID2? Could somebody please explain this real quick. My analysis does not work out. Thank you
  13. Hello, I have to connect a shaft to a bracket. In reality the shaft would be connected with a ball bearing but I try to figure out how to do it in Hypermesh. It is Imortant, because the shaft increases the stiffness of the whole structure. I have acceleration loads, so in my opinion rigids seem inappropriate because the Forces/Displacements have to be transfered either way. How could I do that? Thank you.
