Tutorials

Note

All corresponding files for the tutorials are located in the 4C subfolder <4C-sourcedir>/tests/tutorials/*.

Most of the tutorials use Cubit to generate the finite element geometry, so we will introduce one possible pre-processing method here for the general case. The output format used here is the binary EXODUS format.

The following tutorials are available to show different features of 4C. If you are new to 4C, we recommend to start with a tutorial that fits to your application:

• Scalar transport or thermal analysis: start with the Poisson tutorial.

• Solid mechanics: start with the solid mechanics tutorial.

• Contact mechanics: start with the solid mechanics tutorial and proceed to the 3D contact tutorial.

• Fluid dynamics: start with the fluid mechanics tutorial.

The other tutorials are more advanced and show some of the multiphysics capabilities of 4C.

• FSI: Coupling between fluid and solid mechanics in 2D and 3D

  • Partitioned coupling schemes:

    • Two-dimensional partitioned FSI

    • Three-dimensional partitioned FSI

  • Monolithic coupling scheme: Three-dimensional monolithic solver for FSI).

• Battery simulation: Coupled thermal, mechanical and electrochemical simulation of a battery (battery tutorial).

Preconditioning and iterative solvers: learn how to efficiently solve large linear systems in 4C by comparing different preconditioner options (preconditioning tutorial).
