Conditionning

mohamedlamine's picture

Convergence of Numerical solution may depend on the conditionning of the problem's matrices.

An ill-conditionned matrix produce singulariy cases. This is due to bad shaped elements in

structural mechanics: nearly degenerated elements with zero area (in 2D) or zero volume (in 3D)

The conditionning can be analyzed by numerical algorithms or existing commands in order to

detect these problems.
