  1. Hi puffin In General Negative Volume error happens when solid elements are very deformed and their characteristic length goes to 0. You can avoid this by switching to small strain formulations Also check these previous forum posts about this topic Still if you are not able to rectify it please share the .rad files
  2. Hi flyforever85 Use these options to control various views in Hyperview I also recommend you to check the learning material available in Altair university "Learn Post Processing with HyperView and HyperGraph" https://certification.altairuniversity.com/course/index.php?categoryid=42
  3. Hi kotian You are not getting the .h3d file because the run is getting terminated when the energy error and mass error limit is reached. Open the 001.OUT file and go through the errors and correct it. Interface Id 1 is causing the min time step error. Check the reliability of the time step values you imposed here.
  4. Hi Mehlil Ahmed Can you please explain more with some pictures. As per my understanding if you already have a surface created, then you can use that surface for creating new mesh. Then you can remesh using Automesh panel. In Automesh panel you have the option For Anchor nodes. So you can select those fixed nodes and mesh the remaining surface so that the anchored nodes stay fixed and do not move.
  5. Hi kotian Is it possible to share the files which you are working on.
  6. Hi Ashwani Mittal 1. Go to 2D > Elem types and select all your shell elements and update as below image 2. Assign card image none to lump mass After making these 2 changes the analysis is progressing from my end. You can try it
  7. Hi AshwaniMittal Try Right clicking on the model browser and click create > Rigid walls
  8. Hi Tatiana You cannot open solver separately if you are using student edition. Open the Radioss starter file in student edition and invoke solver from within.
  9. Hi prajwin.a23 I have shared a pdf in the above post which contains the GPU recommendations of HyperWorks. Check whether it helps you.
  10. Hi prajwin.a23 Which pdf are you referring to? Can you please specify it
  11. Hi, I got it solved. There were some unit consistency issues in the model specifically with the gravity card which was causing the error. Now the analysis is running fine. Thanks
  12. Hi All, I am facing an error "INFINITE DOMAIN DETECTED (I7BUCE) IN INTERFACE ID" while solving an explicit problem. As per previous forum posts i understood that we are encountering this error because of flying nodes present in the model. So i have tried with idel=2 for the interface and ismstr-2 for solids but still the error exists. I have attached the rad files here Can someone suggest me a solution? 200707_0000.rad 200707_0001.out
  13. Hi rea2 You can use /DT/NODA/CST which add mass on the node when time step drops Refer the e-book (page 261 onwards) for more details regarding time step control https://altairuniversity.com/free-ebooks-2/free-ebook-crash-analysis-with-radioss-a-study-guide/
  14. Hi Try reinstalling the software to a different location. Also change the default working directory as mentioned in the post below
  15. Hi Mario Messaging is disabled for all users. You can post your queries in the forum
