Simulation - At least two bodies are interfering

Flávia Gonçalves Jul 3, 2018 11:24 AM

Hi! I'm running a simulation on solidworks. It’s a simple simulation though the model is a complex geometry. I'm having problems obtaining the mesh, not because of the parameters but because it says that at least two bodies are interfering. I run the interference analyses with all option selected and there are only coincidente type of interference and it’s suposed to be cause the bodies are connected. I made the assembly from the beggining in new folders a thousand times to make sure that it wasn’t na ocasional error. Do you have any solution? I don’t know what to do.

Hi Flávia,
Can you attach this model to your post. That would let us go through the model and help locate what is causing the interference warning.

  I could't atach the file cause it's too big. See if you can open it with this dropbox link

    Flávia,
    I also did not find any volumetric interferences. I think you are seeing an oddity of how the mesh is trying to represent the geometry. I remade the mesh with new, coarser mesh settings just to see if the mesh itself was creating the interferences itself and the model both meshed, began the solver, and gave me some results (done in 2017 SP5.0):
    
    You may want to try remaking the mesh to get around the warning on your end.

      What parameters do you use? I'm trying with coarser meshing and it always detects interference

        These were the mesh parameters I used for this test:
        Additionally, I set 'Incompatible Mesh' in the definition of the 'Global Contact Bonded'.

Hi,
I have similar problem as the original post.. my head is ready to explode (newbie in simulation, but been using SW for a while already) how to address the "two bodies interfering" error before my static simulation proceeds.

I have attached the zip file for you to look on..

My assy has no interference detected on assy.. and I also tried making the mesh coarser but to no avail..

Appreciate very much your help;.

Rgds,

Jiro

  Hi Rogie,
  I ran 'Interference Detection' on your assembly using these settings:
  
  The results showed that there were two non-zero volumetric interferences on your model. You would need to remove these before continuing with Simulation.
