ANSYS Workbench, line body model, different cross section

[JasonNicholson]

I am trying to run a line body model with different members having different cross sections. Are any of you familar with the Line bodies and how to allow them to have different cross sections?

For each line body that needs a different cross section, create it as "frozen". This way, there will be many bodies defining the line part. If each are to be joined (6 dof constrained to eachother) then select all bodies and make a multi-body part.

bfillery,

I have tried adding them as "add frozen." This does allow you to use different cross sections. However, the issue of this is ANSYS Workbench does not connect the the bodies at the connection points. This is best seen by drawing two line bodies connected at a point and then running a modal analysis on the two line bodies. The mode shapes will show the two line bodies disconnected. This implies that the main issue is connecting two line bodies of different cross section. One would think a that "contact" or "spot weld" would be the answer but the ANSYS workbench help and tutorials never address contact between line bodies.

So the real question may be how do you connect two line bodies that have different cross sections?

bfillery,

Thanks for "multi-body part" suggestion. I had not made a part of this sort before but knowing it existed helped figure out how to make one. Just selct all the bodies to be joined and right click and select "From New Part."
