*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.

Definition

Field	Contents	SI Unit Example
`OPTION3`	ID. Include a contact identifier and title
`inter_ID`	Contact interface identifier. (Integer)
`Title`	Contact interface title. (Character, maximum 70 characters)
`SSID`	Set or part identifier, secondary side. (Integer)
`MSID`	(Optional) Set or part identifier, main side. (Integer)
`SSTYP`	Input set type for secondary side. = 0 Segment set ID = 1 Shell element set ID = 2 Part set ID = 3 Part ID = 5 All parts (`SSID` is ignored) = 6 Part set ID. All parts are included in the contact except the one defined in the part set ID = 7 Subset set ID (Integer)
`MSTYP`	Input set type for main side. = 0 Segment set ID = 1 Shell element set ID = 2 Part set ID = 3 Part ID = 5 All parts (`MSID` is ignored) = 6 Part set ID. All parts are included in the contact except the one defined in the part set ID = 7 Subset set ID (Integer)
`BOXS`	Box number. (Integer) (Optional) Only secondary nodes/segments inside the box will be included.
`BOXM`	(Optional) Box number. (Integer) Only main segments inside the box will be included.

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.
