    help stress simulation error split line

      Hi

       

      I'm a rather new user and have some problems regarding the accuracy of the simulated

      static stress study. I have made split lines were I have applied fixture,loads but the stress deviate

      a lot around the edge of the split line for the fixture compared to the overall stress. I have tried different

      meshing (adaptive, smaller mesh size etc) but still the same result. How to remove this

      error and get a smooth and accurate stress calculation over the hole part? I want to simulate as accurate

      as possible to find the max von mises of the complete part but as it is know the max value

      seems incorrect due to the problem as mentioned.

      Attached is my part.

       

      Grateful for detailed help

          Please post some pictures of what you're concerned with. I think you're talking about highstress at the boundary between your model and a fixture. In that case, take a look at some of the conversations on the forum about stress concentrations and singularities. It is unlikely your restraint is really as stiff as you've made it and you need to add the next part to your analysis to "soften" the restraint at that point.
