    Computers back in the day, what value?

    In many cases the companies in the 70's did not own their own hardware or license the software. In my instance we rented time from Control Data ( Old line supercomputer company). This meant a trip to their facility with a data deck of punch cards, submitting this pile of cards, and running a...

    Mimic Weld Seam/Splice

    I don't have an example but a couple of thoughts come to mind. Are you specifically interested in the stresses on or in the weld? Normally you would only be interested in the stresses in the parts and not the joints. Many times bolts aren't modeled for example. I don't know what the rest of...

    boundary conditions in cosmosworks.

    A couple of thoughts come to mind with this one. If you are doing frequency analysis the default condition globally bonded. This will prevent the model from coming apart. You can however do a couple of things with the restraints. Where the floor meets the legs try restraining the edge. Or if...

    What are CosmosDesignStar limitations

    DesignStar is a very good package, primarily used for analyzing CAD files produced by programs other than SolidWorks. It comes in 3 versions with increasingly sophisticated capablility. The Designer package deals with Linear problems, but not frequency, buckling, fatigue,composites or problems...

    Solid bodies and surface bodies

    Yes I have meshed surfaces, but I believe they must be meshed as shells because they have no thickness. This can be done by when the study is created by asking that the study use shell elements. When you open the part or assembly the shell is meshed by picking the surfaces individually. This...

    Solid bodies and surface bodies

    I see that no one has responded to this post. In general you have to mesh all of the solid bodies in an assembly as solid bodies. Mixed meshes are possible but are used when sheet metal and solid bodies are combined in the assembly. As you point out this does cause a lot of computational time...

    Thin shell assembly meshing difficulties

    I have the same problem with CosmosWorks in shells. The problem is that the "Active" side of the shell needs to be connected to active side of the shells of its adjoining parts. This can lead to some Mobius strip types of arrangements. What I have found that helps is to create the shell by...

    apply displacement instead of force

    If the model becomes "unstable" with force application but not with displacement you may need to consider how the model is constrained. A displacement is a constraint on motion. Force application makes imposes no constraint on the possible degrees of freedom of the model. Also, I like to...
