Meshing multiple element types in ANSYS Workbench
Meshing multiple element types in ANSYS Workbench
(OP)
I am currently trying to create a frame with floor slabs in the ANSYS Workbench environment. My preivous models have all been shear walls only, so only Surface Bodies have been needed. My new model has walls and a steel frame, I have modeled walls as surface bodies, and beams as line bodies. For some reason, I cannot share topology between a surface body and a line body.
My question is, how do I create continuous mesh in ANSYS Workbench where a line body and a surface body share an edge?
In previous models, where I only had shear walls, I would form all Surface Bodies into a new Part in Design Modeler. This gave me the continuous mesh when I moved the model into Mechanical. Unfortunately, this is not the case when I have line element s included in the geometry. Please help!
Thank you all.

Unfortunately, our client has asked for .inp files only so they can review the models we are generating in an older version of ANSYS APDL. That is why I need to generate a compatable mesh between the line and sheet bodies, because as far as I know APDL doesn't have the MPC option.
RE: Meshing multiple element types in ANSYS Workbench
You cannot simply join the elements and call it a day due to the extra degree of freedom that line and surface elements have, rotation. You need to use constraint equations to tie down the rotational DOF. The only place where a conforming mesh or a standard contact pair might work is a lap joint. Embedding the elements as you suggested may make your part too stiff near the interface.

It looks like I will be spending some time modifying my model. Thank you for pointing that out to me.
