THEORY: Outline of some methods used for the numerical resolution of geodynamic problems (Finite Difference Method, Finite Volume Method, Spectral Method, Finite Element Method). Properties of Consistency, Stability, Conservation, Boundedness and Accuracy of a numerical method.
Finite Element Method: Introduction to discrete systems. Discretization method of a continuum in a set of finite elements. Reference to a simple elastic system to introduce the concepts of Nodal Forces, Nodal Displacement, Stiffness Matrix.
Generalization of the Finite Element Method. Form Functions and their properties. Integral Form equivalent to a differential equation. Weak Integral Form. Weighted Residue Method. Galerkin Method. Outline of some numerical integration methods (1D Quadrature. Newton-Cotes Quadrature. Gauss Quadrature).
LABORATORY: Elements of programming (Fortran language) and writing of a simple finite element numerical algorithm that solves a simple process.

Prerequisites for admission
Basic knowledge of programming, integral calculus and linear systems.
Teaching methods
The lessons will take place in the Laboratory of Numerical Modeling of Geodynamic Processes. There will be both traditional lessons on the blackboard and lessons through the use of PowerPoint projections.
During the practical laboratory hours, students will have access to a computer where they can implement, with the support of the teacher, a numerical algorithm for the simulation of a simple process.

Assessment methods and Criteria
The exam consists of two tests:
(1) A practical test in the Laboratory (maximum duration 4 hours) during which the student will be asked to modify the numerical algorithm implemented during the lessons and to write a report with discussion of the new results.
(2) An oral test that aims to verify the knowledge of the topics covered during the lessons.
Part of the oral test will consist of the discussion of the report produced during the practical test.
Passing the practical test is preparatory to the oral test.
The practical test will take place at least two weeks before the oral test and on a date to be agreed with the teachers responsible for the course.
The oral test will follow the official schedule published on the UNIMI website.
