I wanted to know that can we have contact between Beam Elements and Shell elements and what Card is to…

You can use RCFORC data written for contact transducers (*CONTACT_FORCE_TRANSDUCER_PENALTY) to extract any contact forces. Contact transducers are used to record contact…

Edge-to-edge contact can be treated in LS-DYNA via the following three contact types: *CONTACT_SINGLE_EDGE *CONTACT_AUTOMATIC_GENERAL *CONTACT_AUTOMATIC_SINGLE_SURFACE with SOFT=2 and DEPTH=5
READ MORE
In general, *CONTACT_AUTOMATIC_SINGLE_SURFACE, *CONTACT_AUTOMATIC_GENERAL, or *CONTACT_AUTOMATIC_NODES_TO_SURFACE should handle a beam-to-shell-surface contact situation. All of these contact types take into account thickness offsets. The first…

Automatic vs. Non-automatic: Automatic contacts are recommended for most explicit simulations. Non-automatic contacts (in which contact orientation is important) are…

The contact stiffness is not affected by the time step size, when SOFT=0 (*CONTACT, Optional Card A). It can be affected, if SOFT=1 and…
