4. B modeling

4.1. Characteristics of modeling

The modeling is D_ PLAN, only the edge of the frame is represented. Two calculations are performed with different pairing options, contact algorithms, and linear solvers.

4.2. Characteristics of the mesh

Number of knots: 558

Number of meshes and types: 160 QUAD8 for the plate and 1 SEG3 for the frame.

4.3. Tested sizes and results

First calculation (no geometric update, algorithm “PENALISATION”, solver “MULT_FRONT”)

Identification	Reference type	Reference value	Tolerance
\(\mathit{DX}\) at the point \(A\) instant \(1.0\)	“SOURCE_EXTERNE”	2.86E-5	5.0%
\(\mathit{DX}\) at point \(B\) instant \(1.0\)	“SOURCE_EXTERNE”	2.72E-5	5.0%
\(\mathit{DX}\) at the point \(C\) instant \(1.0\)	“SOURCE_EXTERNE”	2.28E-5	5.0%
\(\mathit{DX}\) at point \(D\) instant \(1.0\)	“SOURCE_EXTERNE”	1.98E-5	5.0%
\(\mathit{DX}\) at the point \(E\) instant \(1.0\)	“SOURCE_EXTERNE”	1,5E-5	5,0%

Second calculation (no geometric update, algorithm “PENALISATION”, solver “LDLT”)

Identification	Reference type	Reference value	Tolerance
\(\mathit{DX}\) at the point \(A\) instant \(1.0\)	“SOURCE_EXTERNE”	2.86E-5	5.0%
\(\mathit{DX}\) at point \(B\) instant \(1.0\)	“SOURCE_EXTERNE”	2.72E-5	5.0%
\(\mathit{DX}\) at the point \(C\) instant \(1.0\)	“SOURCE_EXTERNE”	2.28E-5	5.0%
\(\mathit{DX}\) at point \(D\) instant \(1.0\)	“SOURCE_EXTERNE”	1.98E-5	5.0%
\(\mathit{DX}\) at the point \(E\) instant \(1.0\)	“SOURCE_EXTERNE”	1,5E-5	5,0%

4.4. notes

The results obtained are close to the external source to within 5% (code mean). The linear solver has no influence on the results.

The calculation without geometric updating validates the hypothesis of small slips here.
