  1. thank you very much!! i imported the dummy in HyperCrash with Radioss V2017 user profile ang got some Errors: i was able to fix all errors except of the Skew Frame Cards error. May the Skew Definition with free nodes be problematic for the calculation? The error only occurs in V2017 user Profile. Thanks in advance and best regards
  2. Hello, where can i get a RADIOSS dummy model for hypercrash? best regards, HH
  3. i wasw able to fix it by increasing the number of Integration potins
  4. Hello, I'm using the MAT22 material for dynamic calculation with accelerations up to 16g. I'm getting a weird stress plot: The energy error is increasing at once: I'm using the settings as follows: The error only occurs in parts where plasticity is reached. Thank you for any advise, best regards
  5. Hi George, do you have new informations regarding my issue? best regards, H. Huebner
  6. Hello George, Can you please share your model with .h3d files?
  7. When i Isolate the core i get the same results as well. Do not understand why it works in your model. Did you Change anything in the model? Did you change the orientation by changing the skew? Can you please share your model with .h3d files?
  8. Hi George, how exactly did you Isolate the core? Did you delete all components accept of the core in the radioss file?
  9. Hi George, The shear modules are different in my model (G23=25; G13=40). So actually the shear stress results should be different if i Change the skew even if E11=E22. Do you have any idea why it does not work?
  10. This is the same material model, with E11=E22=1; G12=25; G23=40; The shear stress is direction dependent as you can see. Therefore a Change of the skew should Change the results. In the single element case it does, but in the main_Retainer_0000.rad model it does not.

  12. I checked it already in HyperCrash and HyperCrash takes it into acount. But i get the same results anyway if i change the skew. The right models skew is rotated 90° by the z-axis but the results are the same:
  13. Hello George, please find attached the model files main_Retainer_0001.rad MaterialDataBase.rad Retainer_0000.rad main_Retainer_0001.rad
