I`ve drawn a steel structure in SW and want to do a static analysis. Here is what happens:
When I open the static study I get his message:
"Problems have been found while creating joints due to short beams and wrong neutral axes of them. Check the highlighted beams and their neighboring beams".
I just click OK. (Is this something that will make any troubble?)
When I have made the fixtures and appplied the force/gravity I run mesh. Then I get the message:
"One or more joints lie inside solid, and cannot be bonded. Model may not be stable"
I press OK. And then it try to start meshing, then this message appere:
"At least two bodies are interfering. Do you want to check interference?"
I find some parts that interfere, about 0,000123mm. But it`s very complex to do the changes. So I choose Global Contact – Incompatible Mesh. Then run mesh, the meshing works!
New message: "Beam is not properly bonded to shell/solid". How do I bond?
I change all the parts to solid, then run mesh. Then run analysis
Model is unstable. Check that you have applied adequate fixtures to stabilize the model.
Here I use the "Contact Visualization Plot" and see several parts that don`t have contact. So I think I need to set some connections. I use the "Rigid Connection" and chose the faces of the parts. Then I run, and it works. But is the "Rigid Connection" the best connection for these parts. They will be welded when I manufacture the product, what connection will make the most precise study you think?
Can I do this analysis with beams? If so, how do I fix the neutral axes and how do I bond them to shell/solid?
I have attached a file of the model. Hopefully someone can help me, this is a little-bit frustrating
For the beginner better to practice FEA from the online help. The case is little bit difficult for you to practice currently.
Please post your project work condition here including STEP file(s) if you want to get result, maybe some guys can do it for you.
