    mixed mesh

    Juan Montiel

      Hello everyone,

      I am running SolidWorks 2008 with CosmosWorks, trying to learn the software so this was the most economical version of SW I could find.

      I have created a model of a pipe that cantilevers and splits into a Y at the ends.

      While I was able to run the analysis with a vertical load on the pipe, I cannot get it to run with moment, which is the most important part of my analysis.

      Knowing that a solid mesh has only 3 DOFs, while a mesh has 6 DOFs (that include rotation), I created a mixed mesh of my pipe and added a plate to cover the ends of the Y to designate (by defining the selected surfaces) them as a shell to add the moments.

      My question is, after I set the properties to the Solid and Shell members, why does it only mesh the shell element and ignores the solid elements?

      It's baffling that moments cannot be added in a easier manner.

       

      Thanks for reading my post,

          a picture here would be really helpful

          or post the model

           

          is one part not meshing all together or is it maybe excluded?

              Thanks for the reply Jared,

              I have attached the model.

              My background is with AutoCAD and FEA software with shell and beam elements.

              Please criticize me with any part of the model since I am learning.

              Here are a few notes on the model:

              I could not get the model to run if I did not merge the extrusions, so all my members have the same properties but I want different properties.

              Tried to create a shell mesh to apply moments to the model since they cannot be applied to a solid model.

               

              Thanks for you help.

                  what is your goal with this particular analysis?

                   

                  what is the simplest level that you can start with?

                   

                  the reason i ask this is that i do not have access to cosmos2008 to even check what i suggest existed back in those versions

                   

                  regarding a moment, remember that you can apply a moment through the force/moment loading condition
