  1. Hi all, In Hyperview, what is the difference between strain(t) , plastic strain(s) andstrain along thickness(s) in RADIOSS model? I have material elongation as fail threshold. Which result type should i use? Thanks in advance.
  2. Hi all, I am using Radioss and i want to see forces is applied on bolts by creating time history on spring. I created pretensioner spring for a bolt. But ın Hypergraph, forces on bolts occurs very large. What is the reason of this very large force ? Is there any way to see forces on bolts?
  3. Hi Sanjay, When i apply this model as bolt, there will not take place different results between usage of hole and usage of slot. I want to find out differencies between usage of hole and usage of slot. Is there any video or solution for this issue ?
  4. Hi all, Is there any way to model bolts apart from rigid to measure forces on bolt? Could you please share a model or video ? Thanks
  5. And even if i create solid circle section for my beam , the section type transforms generic section automatically when i import the model again. Why it happens always ?
  6. Hi all, Is there any possibility to create beam2n in Radios? Because there is beam3n at everywhere and when i use beam3n in my model, beam element aligned error occurs. What should i do to solve this poblem ? Thanks in advance.
  7. is this /FAIL/TAB1 available for RADIOSS 13? and is there any example to create this fail model ?
  8. Hi all, What is meaning of Gismo used in LS-Dyna ? What is equivalent of the Gismo in Radioss ? Thanks in advance.
  9. Hi everyone, How can i get the squareroot curve of the two curves in Hypergraph ? Thanks in advance.
  10. Hi all, How can i sum 2 curves to get 1 curve in HyperGraph ?
  11. Hi Rahul, Even if orientation of the bolt changes, is y and z always shear force ?
  12. Hi everyone, How can i see the shear forces on the spring used as a bolt in my model ? Thanks in advance.
  13. Hi, I have run this model both with foam and without foam. ı have seen negative internal energy just in model with foam. and i want learn that negative internal energy on foam is important problem or not ?
  14. Well, is negative internal energy serios problem ?
  15. Hi everyone, I have found 500 joule negative internal energy in my model. Is it serious problem for my result accuracy ? Note : My model consists of foam and metals Thanks in advance.
  16. Hi everyone, What should i do to not get energy error except Gap_min in contacts ?
  17. Hi everyone, Which value of LAW70 of foam should i input or increase or decrease to not get any energy problem under huge loads during run in RADIOSS?
  18. Hi everyone, How can i convert LS-DYNA model into RADIOSS completely or most effectly?
  19. Hi everyone, i want to deform the seat foam but the foam deforms very bad in Hypercrash. How can i deform the foam very well in Hypermesh or Hypercrash or anything else way?
  20. Is there any possbility to see these node coordinates in rad or out file after running?
  21. Hi everyone, I can find the coordinates of nodes in rad file for Radioss before running the model but i can't find the coordinates of nodes after running model. In which file can i find the coordinates of nodes after running model ? Thanks in advance.
  22. Hi everyone, I have a model that has duration of 300ms. When it runs, NaN fail in the pic below occurs at 110.ms. in RADIOSS. What is the problem about my model ? Thanks in advance.
  23. Hi all, Is there anyone who has criteria and parameter file of 5mm mesh size to use in Batchmesher except default? Thanks in advance.
  24. Hi all, There are 2 parts with 5mm gap. How can i get that 2 parts should tie strictly to each other and shouldn't separate from each other when they got into contact ? Thanks in advance.
