Hi everybody!
I want to connect two materials (solid65 and link8) in a mesh. They form an RC beam. the solid65 is the concrete and the link8 is the steel. I want to refine the mesh to connect them.
Can you help me?
How are you modelling the RC beam? I guess you are modelling beam with solid + link elements. Solid as concrete and link as reinforced steel bar.
Considering you have modeled beam as solid body with line bodies dispersed inside the solid body, you can not connect the link elements to solid elements directly as both have different degrees of freedom. Link element has 6 whereas solid has 3 degree of freedom.
You need to connect line bodies to solid bodies by bonded contact. Define bonded contacts between solid and link body.
Hi,
You should check the link.

Nikhil Patil, thanks for answering me,
I did the bonded contact between the solid and the link, but even with that I couldnt make the mesh. Do you have another tip?
can you show how have you modeled your analysis setup? I cannot guess anything based on information provided by you.
After you assign solid65 to concrete and link180 to steel through commands in workbench, you first have to set the mid-side nodes to dropped/element order to linear in newer ansys versions to force workbench to use SOLID65 instead of Default SOLID186 element. after that you have to insert another command in static structural branch to bond the line elements to the solid elements as follows
/PREP7
ESEL,S,ENAME,,65
ESEL,A,ENAME,,180
ALLSEL,BELOW,ELEM
CEINTF,0.001,
ALLSEL,ALL
/SOLU
OUTRES,ALL,ALL
neqit,80
SOLID65 has a well know relation with concrete material in ansys APDL/workbench (through commands). however the convergence issues associated with SOLID65 element and the mesh sensitivity of the CONCRETE/SOLID65 combination was one of the motivations for moving to the Microplane model that tracks the softening behavior of the concrete as it fails, without having to track individual cracks. The microplane model with a newer CPT215 element delivered Force - Displacement results that had no significant mesh sensitivity, and agreed very well with the experimental data. A Technology Guide shows how to use the Microplane model with the CPT215 element. Find the youtube video link below (in Russian language). They are comparing the results of the old method using SOLID65 with the new micro-plane model with current technology elements.
