5. C modeling#

Here we test the 3D changes on a 2D mesh. Always starting from the initial grid, we will impose separately:

a deformation with a field (1, 2, 3) applied to all the nodes
a vector translation (1, 2, 3)
a rotation of 45 degrees along the X axis (rotation out of plane)
a base change of vectors \((1;0;0)\), \((0;1;1)\) and their orthogonal
symmetry with respect to the plane constituted by the point (0,0,0) and the vectors \((1;0;0)\), \((0;1;1)\)

A three-dimensional displacement is thus tested for an initially two-dimensional mesh.

5.1. Characteristics of the mesh#

The mesh has a single element of type QUAD4.

With a deformation of the type “TRAN” according to the vector (1, 2, 3)
