  1. Hi, I am trying to simulate a sheet metal stamping in RADIOSS2017 and I want to simulate the dynamic relaxation of the sheet after the plastic deformation. I'm trying to use the card DYREL in which I set the Tperiod equals to 1000 one time and equal to 1500 another time and I obtained two different results. I set these two vaules by suggestion of my Professor but I have not clearly understood what is this Tperiod and why using different values I obtain two different results so I would be glad if someone could explain it to me. Thank you
  2. Ok, I tried and it actually worked. Thanks a lot for the answer.
  3. Hi, I'm following a tutorial of my teacher about a non-linear quasi-static analysis in which there's a temperature gradient. He is using the 2013 version of HM but I have the 2017 one and so I think there is a problem in setting the loadstep. In fact in the loadstep of the 2013 version appears the keyword TEMP in which I can set the load collector for temperature, but in the 2017 version this Keyword misses, so how can I set the temperature load collector in the linear static analysis?
  4. Ok, thank you so much for the help.
  5. Hi, I have a solid model which I imported in HyperMesh to do a linear static analysis. The solid is divided in two solids which I tried to merge but the SW says that they don't share any surface. I attach below the pictures of these two solids and their surfaces I thought were coincident. How can I make this two surfaces coincident in the way the two solids share the same surface?
  6. Hi, I have a solid which I trimmed with the function solid edit to make it mappable in a way to mesh it with solid map. After I trimmed that I used the solid map but the elements in the inferfaces surfaces between the parts I created have no nodes in common. Is there a way to make them with common nodes avoiding to do an equivalence after creating the mesh?
  7. Hi, By the theory of the dynamics of the mechanical system I know that a modal analysis is done without loads because his purpose is to find the normal modes of a body, but I've been asked to make a normal modes analysis in HyperMesh on a component which has a concentrated and constant load of 800 on it. How can I include this load in the loadstep to set and run the analysis?
  8. Hi, I would like to know what is and how it works a DAREA constraint.
  9. Hi, I would like to apply a load of 8000 N but I don't want to apply it on a single node; in fact I want the load to be distrinuted on a face of my component. How can I set it in my analysis?
  10. Thank you a lot for the explication.
  11. Thanks for the answer, so I have another question: how can I know if the analysis converged? I mean, if the analysis ends and the analysis' results are available to see in hyperview did the analysis automatically converge? Or the analysis just ended and the results may be available but completelly wrong even if the Optistruct file .out says the job is completed?
  12. Hi, I have just set a non-linear quasi-static analysis with a contact suracface but I'm non sure if the results I obtained are corrected. In the loadcollector with card NLPARM I created, I filled the NINC field with the value 20, but I did it haphazard. Is there a value I have to set which is the best or does it depends on the load I have in the analysis? the forces I have is about 40000 N. Should I increase the value in NINC or should I decerease it? Thank you
  13. Hi, in solid map if I want to mesh a single component and I select one volume under the voice volume to mesh I can choose between surfs and solid. Which is the diffrence between these choices?
  14. Hi, if I want to model a component with some 1-D elements I have some choices: I can use a PROD element, or a PBAR, or a PBEAM. Which is the differnce among these elemetnts? Could someone explain it to me pls?
  15. Hi, I would like to calculate the mass of my component in HyperMesh (I've already ceated the material collector with the features of the material like density), otherwise I would like to know if it's possible to calculate the volume of the component. Thank you
