  1. Hi Prakash, Ok. It only affects my time step. But it does not affect my computational time (time per time step) a lot? Best, Jonas
  2. Hi! If I add a rigid shell object with around 2000 trias to my simulation in order connect two components, would this slow down my simulation much? Or does a rigid object not really has influence on my computation time. Best, J
  3. Hi Tinh, Ah, I got you! I first had in on 431 (from the command file), but found this "431" a little strange and thought maybe this is the cause for the error. That's why I tried out with THICK which is the property name and it seems to work. However, the initial issues remains. Does it run for you in batchmode?
  4. Hi Tinh, I try to set a property to the thickness 0.1. The property card is a shell element and its a radioss property card. Was that your question? cheers, Jonas
  5. Hmm.. tried it out with "hm_framework loaduserprofile RadiossBlock Radioss2017" but doesn't change anything... Could there be another reason?
  6. Hi, I have a tcl script that runs without any issues in the normal mode. However, as soon as i run it in batchmode (-batchmesher - noconsole) I does not run thru anymore. I figured out that the issue arises from this command: *setvalue props id=1 STATUS = 1 THICK=0.1 I just choose there a property and set the thickness value to 0.1. What is the problem with that in batchmode? Cheers, J
  7. Hi! I wanted to ask how I have to choose the parameters to get the Yeoh and the Neo Hookean material using Law 42 in Radioss: For Mooney Rivlin it is explained in the documentation: a1 = 2, a2 = -2, mue1 = 2, mue2 = -2 How is it for the Yeoh and for the Neo Hookean? Best, J
  8. Hi Prakash, Hmm.. I tried to go thru the ppt-presentation step-by-step. However, it is quite difficult, since I don't have any background information about what I'm really doing with all these environment variables, and scripts, ect... for example I stuck at slide 28.. how do I generate this dll file? Is there a documentation that shows it a bit more precise? And could you also explain me the basic principle: Is it correct that I write a user subroutine (using Fortran coding syntax) that has certain input and output variables? I then have to define in my engine file which elements are computed by this subroutine and also have to define the input variables ? The solver than calls at every iteration the subroutine (using the provided subroutine arguments and uses itself the outputs to continue the computation)?
  9. Hmm, is there a simple way to adapt the files without being expert with user-defined materials? Or is there no way around to work deeply into this topic? Thanks for your help, Best, Jonas
  10. Hi Prakash, Do you have any news on the topic? Best, J
  11. That would be very nice! Thanks a lot!
  12. Hi Nachiket and Kadu In Abaqus this material was used: It is a a Uanisohyper subroutine. The subroutines (using Yeoh and Mooney-Rivlin materials) are attached as well. Thanks a lot for your help! Yeoh.for Mooney_Riv.for
  13. Hi Prakash, Thanks a lot for the reply. Do you have an explanation why I don't get a non-linear angle to moment curve when I bend a block of this material. When you look at the image, this is what someone got with abaqus. On the left side the 2nd curve from the top is with the mue1 and mue2 constants that I showed you here. But in my case when I work with the same constants my disc stays always linear (only stiffness changes). Best, J
