  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
  16. Hi Adarsh Kumar The ideal shape for a brick element is a cube. Warp angle is calculated on faces (quadrilateral) of a hex element. It is the angle between the planes that form by splitting the quad element. Ideal value = 0 (Acceptable <30 degrees)
  17. Hi aymanalsukhon You can import .dat file into Hypermesh, but currently Dytran interfacing is not available with HyperMesh. However you can try out the explicit solver Radioss, where you can define Kinematic constrains
  18. Hi QuentinB Is there a specific reason why you are applying pressure? or else you can use this suggestion and try out 1. Select all the nodes of the surface area in contact (white color portion) and make it as rigid. You can use the calculate node and multiple node option inside the rigids panel. Input the mass of the block as force into the master node of the rigid. This will equally divide and apply the force exerted by the block to all the nodes, which will give reasonable result 2. Also the contour image will show the deformation according to the scale factor you have provided. So check the actual deformation values of the deformed region and interpret the result; the deformation may be too low
  19. Hi QuentinB How did you apply the pressure load. Will it resemble a distributed load along the structure?
  20. Hello aymanalsukhon Can you tell us the format of the file to be input. If it is .dat or .nas then we can import
  21. Hello Julio Apart from the e-book "Practical Aspects of Finite Element Simulation" please refer the composite e-book also which specializes on composite modelling https://altairuniversity.com/free-ebook-introduction-to-practical-aspects-of-composites/ Also refer composite tutorials from online help
  22. Hello Tony Qu Please have a look at the example RDE:0400 from Radioss example guide. This may help you
  23. Hi kandiyal There is no particular step in HV like that. You have the option to split window. you can split the window > load 2 different results in 2 windows and compare
  24. Hi Shahzaib Ilyas Yes, Altair does provides e-Learning subscription to students for free. Please have a look at the following learning resources, The HyperWorks Student guides / eBooks - https://altairuniversity.com/free-ebooks-2/ Altair's Academic Learning & Certification Program - https://certification.altairuniversity.com/ The full HyperWorks HTML documentation (part of your installation) provides a thorough, searchable resource to find detailed information about HyperWorks, including an extensive set of tutorials. An extensive collection of interactive training videos (with audio) covering the most essentials about interacting with the graphical user interface, basics of geometry cleanup, introduction in 2D meshing, analysis, debugging, topology optimization, and post processing (visit the learning library https://altairuniversity.com/learning-library/ for more information) Our YouTube channel - https://www.youtube.com/user/HyperWorksUniversity Note that your students can always ask us questions while learning using the Altair Support Forum - https://forum.altairhyperworks.com/
