I'm relatively new to COMSOL but I haven't had much luck finding a solution.
I had an assembly in SolidWorks made of 3 parts. I created a new SolidWorks part file which had the 3 parts mated together correctly and saved it. I imported that SolidWorks part into COMSOL. COMSOL recognized it as having 3 domains which I assigned different material properties to. I fixed the bottom and applied a load on the top. When I ran a tetrahedral static solid model test, the stress was what I expected for the top layer but it appears that it did not make it to the remaining layers. The stress on one side of the interface is a magnitude different than the other side, right at the interface. I attached a picture of this.
The nodes seem to align at the interface too. Even when I used the same mesh size for the entire model, I had the same issue. Does anyone have suggestions on a solution? I also attached my setup.
I can provide more detail and pictures if needed.
Thanks,
Jeremy
