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.
