    DAREA

    Hi, Can someone please explain in detail what DAREA is, and when it is used? I dont seem to find enough documentation on it. Regards, Vdilip
  2. Hi, You can also try Geom> surface edit> trim with surfs/planes> self intersecting surfs (select the surfaces) > trim
  3. HI Andy, I have used MAT/LAW2. Since it is as side impact analysis, I presume the kinetic energy would come down after impact. I have plotted other energies, all of it are negligible or zero. I am using a meshed cylinder with /RBODY. I have also tried it with the /RWALL option, and the values seem to be the same. What are the friction parameters that are recommended? And also how do I define the inertia? Just to clarify, it is a single component test. Thanks, Vishruth
  4. Hi Ivan, I managed to figure out why the contact energy was that high. It was a modeling mistake. However, the Kinetic energy after impact still seems to be very high. I have used the suggested parameters for the contact ( self contact ). My component does not seem to absorb much energy. What could be the error? Unfortunately , I will not be able to share the model.
  5. Hello all, I am trying to run a pole impact simulation for a side sill. The following are the plots i got for the diff global variables. However, the contact energy seems to be too high, and the kinetic energy even after impact has a very high value. What could be the reason for this? I have used TYPE 7 contact for the self contact of the sill, and also for the contact between the rigid pole and the side sill.
  6. Hi @Pranav Hari I have shared two example files. Could you please check it and let me know?
  7. Hi @Pranav Hari @karthikeyan Thangavelu, I have created the include file. But when i import the solver deck, it shows the following error. Warning: starter Input Deck contains Keyword which is CURRENTLY UNSUPPORTED in HM present at line number 27 Summary:Feinput finished with 0 errors and 1 warnings. My input deck has only 26 lines. I've also tried it with a more complex file which I could run before, but it shows the same error.
  8. Hi @Pranav Hari, For radioss to be able to read the include file, what should I save the file as? What should the file extension be?
  9. Hi @Pranav Hari, So the simplest way of say creating a MAT/LAW2 would be to copy the Example, as shown in the picture below in the text editor ( .rad file ) and edit the parameters as required? Am i right?
  10. Hi @Pranav Hari, I want to know how to work with text files. For instance, I have come across a .k file which contains the material database, which I inlcude in the master model for LS-dyna solver. And similarly a .bdf file for the optistruct solver. How do I create one for RADIOSS, without using the GUI? Thanks
  11. Hello @Pranav Hari , I have an Abaqus material card. I need to convert this to a RADIOSS card. How do i do it?
  12. Hello all, Could someone please tell me how to do the above? Thank you
  13. Hello all, How do I create a material database using a text editor such as Notepad or Jedit, so that I can include it in the Master model as an Include file. I need to create a card for RADIOSS. Is there any documentation or videos that I can watch? Thanks in advance for your answer.
  14. Hello all, I have created a laminate by specifiying different plies and their orientation on ESAcomp. How do I find out the Youngs modulus of the laminate as whole? Is there an option on ESAComp that give the laminate properties, specifically Youngs modulus. Thank you
  15. Hello all, I want to mesh a complex solid with a very small thickness of about 2.5mm. I tried auto extracting the mid surface, but the result seems to be very bad. The surfaces tend to be disconnected, and the mid surface does not look good. What would be the right way to go about the meshing of this part? Any and all help would be appreciated.
