  1. Hello, I'm trying to open a 145MB H3D file in hyperview 2019.1 but it seems to get stuck and go non responsive when loading and saying committing geometry. Is this a known error? The H3D file opens in other commercial post processors, just not hyperview.
  2. Hello, I'm trying to assign a material orientation via a vector through the 2D-composites-material orientation tab for a 3D solid element with the Mat9ort material card. Hypermesh does not change the element material direction saying the reference vector can not be projected for lowlighted elements. Is anyone able to help or offer an alternative method? Thanks, Aidan
  3. Hello, There seem to be many manufacturing solutions available except for short fibre reinforced plastics. Are there any solutions for short fibres part of the Hyperworks suite or partner alliance? Thanks
  4. Hello, I have set the DESMAX in the individual model files but when running the MMO it uses a default value of 80 iterations. How can I change this default?
  5. Hello, Can someone please share the model file for example OS-E: 0845 Control Arm with Local Stress Constraint, control_arm_fine.zip. My Hyperworks hasn't installed any of the example files in the demo folder. Thanks in advance
  6. Thanks for the reply, I have got the simulation to run using hexa and penta elements instead of tetra elements. Is a tetra mesh defined as a lattice structure?
  7. Hello, I'am trying to perform a topology optimization using MMO which has a solid property for a design variable. When I run the MMO I get an error *** ERROR # 7506 *** Current version of lattice structures does not support multi-model optimization . Are solid properties not supported for MMO or is there another problem? Thanks
  8. Hello, I'am trying to create an MMO and I wanted to use the model files from OS-E: 0830 Excavator Arm to help me but they are not in my installed directory. I go into demos/hwsolvers/optistruct and there are model files there but none of the MMO files are there. Can I obtain these files from anywhere else? Thanks Aidan
  9. I've fixed my problem by solving and outputting forces so I can set up the optimisation using only forces and eliminating the need for a spring element.
  10. Hello, I'am optimising a front wishbone for both the left and right of a suspension. My idea is to have the loads and boundary conditions mirrored between loadsteps however there is a spring/damper element that would effect the results. Can you deactivate/ignore elements between the loadsteps? Or is there a better way to combine the optimisation so that the component is optimised for both the left and right tyre loads?
  11. Hi, I have tried both CORDM -1 and BLANK to compare and there is still a noticeable difference in the CPENTA and CHEXA elements.
  12. Hi, It will be difficult to adapt to a PCOMPLS as the material is not ply based. Orthotropic behaviour is due to the manufacturing process.
  13. Hi Prakash, I'am using the PSOLID property card with defaults except CORDM -1.
