7. E modeling#

7.1. Characteristics of modeling#

3D modeling is used in non-linear mechanics.

This modeling tests the creation of empirical modes in mechanics. We take for the base primal and the dual base TOLE_SVD = 1.E-3.

7.2. Characteristics of the mesh#

The mesh contains 27 elements of type HEXA8.

7.3. Tested sizes and results#

We test some values of the primal base (as they are empirical modes, the tests are done to the nearest sign):

We test some values of the primal base obtained by method POD_INCR with TOLE = 1.E-10. The same modes as before are obtained:

We test some values of the dual base (as they are empirical modes, the tests are done to the nearest sign):

7.4. notes#

We cannot say anything in absolute terms about the precision of these values because we are testing values of non-regression, but the two bases produced (in displacement and in constraints) will be tested in the other models to compare with the full calculation.
