Question:
Is it possible to couple members with solid elements?
Answer:
A 1D element (member) cannot be directly integrated into 3D elements of a solid. However, there are tools that allow for coupling.
If a slender component (member) is to be connected with a solid component (solid), it is necessary to pay attention to the correct coupling of these elements when modeling.
1. For example, if a column with an end plate is rigidly bolted to a single foundation, this can be done by means of a "cross connection". Thus, the problematic rotational degrees of freedom may be transferred by translational degrees of freedom. The dimensions of the "cross connection" should correspond approximately to the dimensions of the cross‑section.
2. For example, if a member is encased in a single foundation, the solid should be separated in the member plane in order to ensure the connection between the member and the boundary surface and thus the connection with the solid.
