    MAT9ORT for cpenta elements

    Hi, I have tried both CORDM -1 and BLANK to compare and there is still a noticeable difference in the CPENTA and CHEXA elements.

    MAT9ORT for cpenta elements

    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.

    MAT9ORT for cpenta elements

    Hi Prakash, I'am using the PSOLID property card with defaults except CORDM -1.
  4. I'am studying how a components performance is affected by the materials isotropic and orthotropic behaviour. The image attached shows the same 3d solid mesh using hexa and penta elements but with an isotropic material (top) and an orthotropic material (bottom). I'am using mat1 for isotropic and mat9ort for orthotropic. There is a clear difference in stress for the cpenta elements compared to the chexa. Are cpenta elements fully supported for mat9ort or is this behaviour a result of the cpenta element formulation?

    Error with element energy

    I've checked in hypercrash and not found any initial penetrations. I'm using both type 2 and 7 contacts but I believe the problem is in the type 7. I'm also not sure how to set full integration or whether it is already set. I'm using property 19 SH_SANDW with Ishell 24

    Error with element energy

    I'm trying to run a crash simulation and have encountered the element distortion/extrusion shown in the attached image. I don't know the correct terminology for this so it has been difficult to find solutions online. I believe it is caused by the contact interfaces and I have enlarged the gap min and told the nodes of deleted elements to be removed. There is also failure criteria which seems to have been ignored for these elements because they should have failed and been deleted. Any help would be appreciated.

    Unable to read T File

    Thank you, converting to .abf worked

    Unable to read T File

    I'm running a crash simulation in Radioss and I have requested a T file to be written. When I try and load the T file (T01) in hyperview and in hypergraph an error comes up saying it was unable to recognise it. I set the type to 0 default and I also tried 4 because I believe hypergraph can read that. I think data is being written to the file because the file size is fairly large. Any help would be appreciated. _ront_bumper.crashT01
