Modeling Multi Part Assemblies w/ CosmosWorks 1

[huss43]

I am not a regular user of Cosmosworks but have a question regarding modeling of multipart weldements. Say you have a 3 piece weldment, 2 solid bars in the shape of the letter "L" and a triangular shaped plate gusset. How does one go about modeling this set-up as one piece if I dont want to use 'surface contacts'? More specifically how do I set up this model so Cosmosworks recogizes it as bonded together and not separate pieces.

A couple of years ago a person from a Cosmosworks helpdesk talked me thru a problem like this by setting up another thin walled assembly of the original model and modeling it using shell elements. But I dont recall the exact method. Any insight on these questions would be appreciated.

Looking forward to a response!
Thanks - Mark (hitest70@msn.com)

Hi Mark,

Typically you create a weldment within a single part in Solidworks, such as your "L". You triangular gusset you could create as an extrusion off of this weldment while not merging bodies. You would then add fillet welds if you prefer to simulate the welded gusset. Or, you could merge the bodies making them a solid part with no weld. That is the best way to simulate proper weldments with Cosmosworks, as a single part.

Now, within an assembly, you make your mates of the various parts locking the assembly together. Solidworks will not allow the assembly to break apart, in which you can proceed to simulate it within Cosmosworks. It knows its an assembly, but the assembly will be locked together (even if in real life the weld split or something similar). Make sure the assembly is fully mated. The assembly method of testing is the best way to test dissimilar materials, as you cannot do that within a single part.

I hope this helps. Shout out if you need more help.

When you setting up the analysis of the assembly in Cosmos, set the "global contact" setting to "bonded".

You also could save the assembly as a part file, after you added mates ofcourse.

try to define your desired contact using by Gap/contact in the study manager tree, as Dear ShaggyPE wrote "Bonded" is selected by defult,but you can change it as a "Free(No interaction),No penetration,Bonded(No clearance), also you can perform compatible or Incompatible method for mesh generation.

Hey I have something similar. I have an assembly and I want to do a simple point load test using the free simulation wizard cosmos. It tells me I need to run the simulation wizard to use cosmos yet my assembly is static.
