  1. Hello C2C experts, I am doing casting simulation with carbon steel material. But I found only 2 types: AISI-1008 & 1026. Could you advise how to do if I want to simulate AISI-1030? Thank you.

    Problem with .stl filles

    Most of casting software use STL import (3D scan data). But you can use Inspire Cast to import step/parasolid/... files with good geometry quality. Another method I overcome this issue for complex geometry (scan data) by using Simlab or HM to create good mesh >> export to STL >> Click2Cast.

    Cannot open 2nd HM session

    Thanks Tinh for your advice. I cannot open 2nd session even wait for hours. Actually, I already called Altair Support and found this issue only happen in user account (not full writing permission). Admin account is fine. This bug was fixed in v2017.2.2. We can close this topic.
  4. Hello HM experts, My Hypermesh(v2017.2) and my colleagues recently have had a serious issue. We cannot open 2nd HM session, we can open only one. I checked on Task manager and saw few opengl.exe running in process tab but the size is smaller (~250 MB) than the 1st one. Could you have any comments and advice how to solve this issue? Thank you!
  5. Hi HF, I am new to Inspire Form(IF( and try to use it. But I cannot found where and how to input cushion force in IF. Same as for Friction parameters in IF. Any comments and advice are very much appreciated. Thank you coud
  6. Hi Forming Simulation experts, I am trying to create my own material in Inspire Form but do not know how to input true stress/strain curve. I am new to Inspire Form (I know how to do this in Hyperform) Could you advise how to do? Thank you.
  7. Hi Acusolve pro, My company has just implemented Micro Trend Antivirus system recently in whole organization. However, our CAE department cannot open AcufieldView because Trend Micro prevent running *.bat file. May I know any ways to run AcufielView directly rather than using BAT file? Thank you!
  8. Hi, May I know how to straighten lines when drawing sketch in ST inspire?
  9. Thanks Prakash, After reset (Delete some files in working folder) HM, I can rotate model normally. But I still cannot show/hide comps when stay in "add solid faces". However, I already created a script to do this very quickly (4 clicks to create contact group+select master/slaver+contact type). Default HM may requires 20 mouse clicks.

    How to export ST inspire to *.fem file?

    Thanks Rahul for your suggestion. I will keep in mind this. Actually, it takes sometimes to complete generating the meshing. My model is quite big(truck frame). After the green flag appeared, click on that I already have correct *.fem file. P.S: ST Inspire is very useful tools for my creating new design (small or big structure). I am just surprised that there are not so many questions/discussions anywhere else except for Altair Support forum. Thanks a lot of Altair support forum.
  11. Hi, When I add "element" for surface contact in entities editor, I cannot rotate/pan or show/hide components to easily select. Could you have any better method to do this? Many thanks
  12. Hello, I am running ST inspire optimization (v2018.1) but it takes quite long time for computation on my desktop machine. I want to submit optimization job on cluster but unable to Export *.fem file on RUN dialogue as help. The file size is Zero after export. I am not sure any requirement on setting preference or this is a bug on v2018.1
  13. Thanks Prakash for your very fast response as usual. So, it means that accuracy and computation speed is same. So could you advise when we use SET_ELEM, when we use contact_surface?
  14. Hi, To define contact pair (group) in O.S I often create contact surface then create contact group. It takes me a lot of time to choose contact surface for some part. There is another option, I create set (SET_ELEMENT), then point to elements (by collector) to select all. It is a bit faster because I can script. However, I am newbie and not sure which method is better about computation speed or accuracy? Could you advise?
  15. 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?
