CNCAS
Coupled contact for continuous casting
Description
The element has 2 or 3 nodes (linear or parabolic) and is related to a foundation.
Convention: when the element is considered in increasing order of nodes (1 → 2 → 3), the first body is to the left, and the foundation to the right.
This element can be used with law COU2DC as it includes friction and thermal exchange by radiation-convection or with thermal resistance.
This element also uses law BOCHA: it is indeed necessary to know the speed perpendicular to the studied plane (casting speed).
Type: 215
Implemented by: F. Pascon (1998)

Results
Stresses: pressure, tangent stress, thermal flux
Internal variables: The first values are the ones relating to the law (for Coulomb law, this will be: plasticity indicator, dissipation, information on mechanical dissipation in thermal flow). The 6 last values correspond to the contact geometry. They are:
- The segment number of the foundation in contact
- The interpenetration distance
- The jacobian
- NOCO the contact indicator given by CALFON
- The relative tangent rate (in the X,Y plane)
- The thickness
