    Unable to export model file

    I shared the files in the secured folder. The problem is kind of solved, since I can now export it with Hypermesh if I import and export with Hypercrash before.

    Unable to export model file

    I can't share it directly here. I know administrators have a secured file deposit. I'm waiting for their response.

    Unable to export model file

    I'm using Hypermesh version 14.0.130, and the model is supposed to have been created in version 12.0.224. It's the Hybrid III 50e percentile version 8.0.5 model made by Altair. I don't think that I can share it here, but maybe in a secured folder. And yes, my user profile is define as Radioss (Block 140). Can somebody help? JM

    Unable to export model file

    Hi, I'm trying to export a file to .rad format, but I get this message «Unable to export model file», and the message at the bottom-left corner in Hypermesh is «Invalid pointer requested». What can I do to export it? I can save it as .hm though. Thanks JM

    Property type for tetramesh

    Allright thanks! I'll try this! JM

    Property type for tetramesh

    Hi thanks for your response, I'll try it, but for tetrahedron, can we use Isolid=1, Ismstr=1, Iframe=1 and IHKT=1 (I don't find that one) like the mentionned post suggested? Thanks! JM

    Property type for tetramesh

    Hello, I modeled foam with tetrahedral elements and wondered what property should I use? In fact, I understand it's isolid, but what options should I add? It works, but I have hourglass problems I think. It's foam under impact. Thanks! JM
  8. Allright thanks! I'll take a look! JM
  9. Hi George, Thanks for the fast response! I did download the model and it helped me understand a couple of things. I was just wondering, if the model is the exact same that the one in the case study that you provided (http://altairatc.com/europe/presentations/session10/session10_ford_schilling.pdf). In fact, the geometry looks different, but if everything else is the same, it's perfect for me. More precisely, if the model has the same material, the EPP, it's even better. Also, I have an additional question. I was wondering if in law 70, there were parameters to change the shear behavior of the foam. I ''played'' with some of them, but I don't have what I expected. In fact, in pure compression the model behaves like the experimental tests that are obviously in pure compression. However, when I run combined or oblique loading simulations (pure compression and shear), the forces are not the same. If you want more precision on my problem, I'll share it to you. So, if you know some parameters that I can play with to get more of what i want or another tabulated law like 38 maybe, let me know! Thanks! JM
  10. Hi, still no tutorial about foam in Radioss? I'm waiting for it also Thanks! JM

    Missing job completed

    No, but I'm running on Linux, I don't know if it maybe in a processes that is not killed properly between each simulation. Thanks JM

    Missing job completed

    Hi, I got a problem with radioss recently. At the end of the simulation, it is not written "job completed" at usual. And in Hyperworks Solver Run manager, it is still written "running 1 job". So, when the 1st simulation is completed, the 2nd one does not start because of this. Can someone help me please!? Thanks JM

    Hi everyone, I got this error message «RADIOSS INTERNAL ERROR: S3N6» in Radioss window when I launch my file. And this error doesn't appear in the .out file. Any clue? Thanks JM
  14. I got my answer from that question. Thanks!

    Thanks it's working!
