The Structural Mechanics Application contains a series of structural elements, as well as solid elements, constitutive laws and the corresponding strategies and solvers within Kratos Multiphysics.
The application includes tests to check the proper functioning of the application
-
A set of Neumann conditions:
- Point loads (loads applied directly on the nodes)
