Assemblies

[Paul1969]

Will Cosomosworks work on assemblies? I get errors on anything that is not an individual part.

COMOSWorks will work on assemblies and parts. COMOSXpress will only work with parts.

I have the full version of CosmosWorks Professional.

Do you have SolidWorks Premium as well? If so, you could have a problem with your license configuration, making COSMOSWorks run as "COSMOSWorks Designer" instead of the Pro.

Do an interference quick on the assembly. Correct them if there are.

 

[Paul1969]

I ran an interference check and a few came up, I fixed all of them, but it still comes up with the multi-bodies not supported message. All of the parts have been fixed with mates, so I don't see why it would think it is a multibody.

 

[2design]

Try a simple assembly model such as two bars that mate at the ends. Put a contact constraint between the two so you essentially have one beam. Fully constrain one end and put a load on the other end. Solve it to see if this works.

What kinds of errors are you getting. If the other suggestions don't work you could trying doing a shell model assy. Try butting two shell boxes together and running them.

2design,
I created an assembly as you described and cosmos worked fine, it performed a complete analysis. I tried my original assembly and I got the same error message. The model is fairly complicated ( 40+ parts). If one of the mates was missing would that cause cosmos to see it as a multi-body?

badboggs,
The error message is "COSMOSWorks does not support multi-bodies."

 

[2design]

Yes, and worse yet when there is a mate condition but it is not working properly. The best way I have found to degug this is to perform a modal (frequency) analysis using the sparse solver and activate the soft springs options. If it solves it may indicate which contacts are not working or missing.
