  1. Would S2S therefore be a better choice in my case? It may be less 'sensitive' but which is more realistic? Thanks for your all your help.
  2. Ok thanks, I'll give that a try. I have also tried inverting the master and slave contact pairs. Should the mesh size be the same between the components in contact or does this not directly affect the results? Which should be the master or slave? I find that if I invert the contact, I get a triangular effect...
  3. Thanks for the speedy reply! Here is the .out. Mors_05.out
  4. Hi everyone, I'm trying to model a cylindrical section being held between a grip that tightens around it. When I look at each jaw however, I have a contact pressure concentration in one area and I can't seem to find out why. I'm using Optistruct V13 and I use the auto-contact tool to create the contacts between each component. I have checked for penetration between these components and there is none (there is between two other pieces but I do not look at these). I have quite a fine mesh as I'm looking at this specific area (mesh size 0.5mm). Does anyone know what I could do to get rid of this point? Could it be that these nodes are slightly irregular and 'sticking out' slightly from the component? Thank you for any help you may be able to give me!
  5. Hi, I've previously had help from one of your colleagues with my model for which they suggested I do a Mesh-->Check--> Elements-->Penetration as I had a problem with my slide contact surfaces. I fixed the majority of these penetrations with the auto manager (not all were fixed) and tried to relaunch the calculation. However, now my model does not manage to converge and I don't fully understand why, even after reading up on all of the input fields in the contact menu. Any help would be greatly appreciated (model is attached)! Thanks in advance. 151207_MD_01_A-42.hm
