This training course is designed for beginner in the calculation by finite element method. The participant will be able to use CESAR-LCPC in his field of activity: geotechnics, structure, hydrogeology.

Modeling two-dimensional or three-dimensional structures in the CESAR-LCPC framework

• Generating the 2D or 3D structural mesh,
• Processing mesh zones as being either active or inactive on the basis of the adopted construction method,
• Assigning materials elastic behavior, elastoplastic behavior, thermal behavior, …
• Defining boundary conditions in terms of displacements, temperature, …
• Creating loading cases that are either independent or correlated with a preceding computation result (excavation forces, initial stresses, etc.),
• Setting up an iterative convergence routine for solving non-linear problems.

Mastering and utilizing model output

• Verifying the successful execution of computations,
• Querying results: displacements, stresses, temperatures at any point of the model,
• Displaying plastified material zones, along with the displacement, stress and temperature isovalues, etc.
• Conducting use-related verifications on the consistency of results obtained,
• Testing model sensitivity on the basis of both the mesh and the set of selected computation conditions.
