**v1.01.289** ZZZZ289 - Validations of calculations of elementary matrices of incompressible elements
======================================================================================================

**Summary:**

This test is used to validate the calculation of options MASS_MECA and RIGI_MECA of the elements of the following incompressible models: INCO_UPG and INCO_UP. Six models are used:

(A) 3D elements: 3D_ INCO_UPG and 3D_ INCO_UP for a linear and quadratic mesh in small deformations,

(B) elements D_ PLAN: D_ PLAN_INCO_UPG and D_ PLAN_INCO_UP for a linear and quadratic mesh in small deformations,

(C) elements AXIS: AXIS_INCO_UPG and AXIS_INCO_UP for a linear and quadratic mesh in small deformations,

(D) 3D elements: 3D_ INCO_UPG and 3D_ INCO_UP in large deformations,

(E) elements D_ PLAN: D_ PLAN_INCO_UPG and D_ PLAN_INCO_UP, in large deformations

(F) elements AXIS: AXIS_INCO_UPG and AXIS_INCO_UP in large deformations.
