Hey guys,
I have a problem here, im trying a drop test simulation with this attached chassis and everything is fine except mesh, when I run mesh creation, solidworks show me some (a lot) of body interferences between most of the structural members.
If anyone can help , it will be much appreciated.
Thanks!
This is part of the GIGO problem that has plagued mankind since the dawn of time. If your geometry isn't "clean" then you have no hope of getting good information out even if you could run your FEA.
Go back and make sure that there are no gaps between parts; that the parts fit together perfectly (flat or lofted surfaces); make certain that you have cleaned things up so there will be no slivers.
Oh, and check interference in the model.
It seems that I need to work more on those details , thank you very much !
Certainly James has a point that the geometry could be cleaned up a bit more. This would be the best route. This would help for simulation, chassis fabrication, and design of mating components.
You can, however, just edit the joint clearance. Edit the joint group and use "less than 3 inches". After re-calculating the joints the whole thing meshes for me.
You should of course be careful to check where joints were merged. Right click on any purple joint to see the constituent beams. You can edit these manually if need be.
Create a mesh plot of just the mesh with the "render beam profile" option to get an idea how the mesh is approximating the real deal. Look for joints that come together differently than you intended or modeled.
There are two solid bodies hidden in there too. In the simulation tree you can right click on the cut-list and delete it. This way you can see all your beams/bodies at once.
Thank you very much , I will try what you suggest me . regards!
