Deformation exchange between adjacent physical code geometries

Abstract

Physical codes are dependent on a discipline and describe the reality through equations solved on a geometry. Strong links, or couplings, between them are set up to increase the result accuracy, leading to data exchanges. Mechanical codes calculate geometrical deformations which must be tranferred by couplings. Their direct exchange is generally impossible if coupled codes compute with different models of the same geometry (in practice different meshes). Moreover, two meshes can only share border(s). This paper focuses on this case: one mesh must follow the border deformation of the mechanical code mesh.
