Simulation - static analysis fail

[pwr2020]

Not sure if this issue has been addressed previously, but while generating a mesh and solving a static analysis in one structural configuration...all goes well and results as expected. Once a slight change is made to the geometry of the model, I update the assembly components in the study window and proceed to run the analysis. This error keeps showing up regardless of the mesh geometry...

"Number of element nodes is greater than the maximum allowed element number=24120"

Any help would be greatly appreciated!
Thanks!

I think it means, "Get out your checkbook".

Haha, yeah kinda feels that way!

Well, solved it by updating the model and saving all components, then repeating this tact in the study as I mentioned before. Now that that's solved, here is the next mind boggling return from simulation...

"Midside nodes on two edges of an element are merged, element:128267 (reducing mesh tolerance or specifying a higher no. of points for Jacobian check for meshing may help).

I decreased the tolerance to .01 (smallest available) and set the number of points at 29 and "nodes only" to see if that would help. Not only did this not help any, but the node identified changes every time I ask it to run...and ideas here?

Thanks!

Yeah, _increase_ the mesh tolerance.

When preparing a SolidWorks model for FEA it is always a good idea to use the TOOLS/CHECK functionality and find and remove gaps, small faces and edges and generally clean up the model by removing small features that have nothing to do with the FEA giving good answers.
