*CONTACT_FORCE_TRANSDUCER_PENALTY
LS-DYNA Input Interface KeywordAccumulates output for contact forces (from other existing contacts) acting on a given set of nodes/segments determined by set, part or subset with optional selection of interacting main side contact entities and intersection between sets and boxes.
This is a transducer for other existing contacts only and does not create a contact itself.

Comments
- This keyword maps to /INTER/SUB.
- In case only SSID is defined, all contact forces on the entities in selected SSID are accumulated, where MSID is also selected, only contact forces due to interaction between entities in SSID and MSID are included. If BOXS or BOXM are defined, then only entities from SSID and MSID that are also inside the BOXS/BOXM respectively are included for force summation.
