Hello can anyone inform me if there is possible to create variable cross section beam in ANSYS Workbench?

I mean i want to define two cross sections, connect them and create beam not a solid. 

Is there a solution for this problem or we can't do that in workbench?

If you have two line bodies, each can have their own cross section. The line bodies have vertices that are at the same coordinates. In DM, you create a Multibody part by selecting the two line bodies and Form New Part, or in SC, you use the Share button on the Prepare tab. Then in Mechanical, there will be a single node that connects the beam elements on either side that have different cross-sections.

Thanks for help, but is there a way to add script with commands from APDL and connect it to simple line body in workbench, and get proper solution basing on that commands and variable section from APDL?

I expect that is possible but not something I know how to do.

Thats all i ve got, but it creates only one cross section...
