3. Modeling A

3.1. Characteristics of modeling

Cutting:	28 elements in length,
	8 elements in width.

Boundary conditions - loading (three calculations for three choices):

• calculation a: scalar loads and dualization of the Dirichlet condition:

ECHANGE (GROUP_MA =” GRSD1 “, COEF_H_SUP: 10., COEF_H_INF = 10. , TEMP_EXT_SUP = -50., TEMP_EXT_INF = -50.) (GROUP_MA =” GRSD2 “, COEF_H_SUP = 10., COEF_H_INF = 10. , TEMP_EXT_SUP = 50., TEMP_EXT_INF = 50.)

• calculation b: constant load functions and dualization of the Dirichlet condition:

as above, but with constant functions having the same values.

• calculation c: scalar loads and « kinematic » loading:

3.2. Characteristics of the mesh

Number of knots: 969

Number of meshes and types: 448 meshes TRIA6

3.3. Tested values
