3. Modeling A

3.1. Characteristics of modeling

The modeling used in the test case is as follows:

2D elements” PLAN “(QUA8)

Figure 3.1-a: Modeling geometry and meshing

Cutting:	5 QUAD8 meshes along the \(x\) axis
	5 QUAD8 meshes along the \(y\) axis

Knots:

\(A\): knit \(\mathit{M13}\) knot \(\mathit{N39}\)

\(B\): knit \(\mathit{M19}\) knot \(\mathit{N66}\)

\(C\): knit \(\mathit{M19}\) knot \(\mathit{N70}\)

3.2. Characteristics of the mesh

Number of knots: 96

Number of meshes and types: 25 QUAD8, 20 SEG3.

3.3. Tested values
