  1. Hi HW experts, I am doing stamping analysis for solid mesh (pipe). However, I just found few materials for SOLID in Hyperform. I also do not know where to find the input paramters for Hill MMC - law 72 in RADIOSS although try to search on the internet. Could you advise for this problem?
  2. Thank you StuDes so much for your detail explanation!

    Single action vs double action

    Thank you very much Ms. StuDes
  4. Hi all, I am running some stamping simulation with Hyperform but I do not really understand what is different b/w R-Mesh, B-Mesh and Automesh functions? and Adaptivity level (Should be 2 or 3)? I feel so weird when running some model using R-Mesh option (very "bad" mesh quality) but it is still runable. However, I try to create good mesh with "AutoMesh" function but it is not converged.
  5. Hi HF experts, I am new to Hyperform and feel a bit difficult to understand the concepts - "Single action" v.s "Double" action in Hyperform. Which cases should we use "Single" and when should use "Double"?

    spring back effect of clamp

    Can you share with us your model and how do you bend blank? and material?
  7. Hello Hyperform users, I run Hyperform jobs directly on HF environments but it always use only 1 CPU after I restart HyperForm. HF always forget my setting " 'noh3d -nproc 4' after it restarts. Do you know how to solve this issue?
  8. Hi, I am run very simple FE model (2 solid parts contact) drop test. I used contact type 7 for contact b/w 2 models and self-contact (type 7): - I(stiffness) = 4 - Fric = 0.2 - Gap min = 0.5 >> I am not really clear about the meaning of gap min. - I frm =2 - Inacti = 5 However, the result shows contact energy very high? Could you share the reason of high contact energy?
  9. Hi George, Appreciate your prompt support again. I update Penta elements to PENTA6DG and Radioss ran pretty well. Thanks again!
  10. Thank you George very much for your fast response. I have never used thick shell solid. Could you explain the difference b/w normal solid shape element and thick shell solid for application purpose?
  11. Hi, I want to morphing hexa/penta seat cushion with Radioss? I often use P14_SOLID for Hexa and Tetra elements but unable to run with Penta elements? Could you advise for this? Thank you.

  13. Hi Rahul, Thank you so much for your help. But I tried to clean up HM as your recommendation but the issue persists. I will try to install HM again.

    How to read *.tbc file

    Hi Tĩnh. I am sorry for making wrong explanation. I would like to know how to compile my tcl code to *.tbc in case I wanna protect my program.
  15. Hello HW experts, I tried to use "minimum distance" function few times but HV always crashes when I used this function. ( After I hit on OK button on select entity) I refer to the below link document: https://altairuniversity.com/learning-library/minimum-distance-measure-type-in-hyperview/
