# PARTIAL DIFFERENTIAL EQUATIONS AND FINITE DIFFERENCE METHOD

• #### Number of hours

• Lectures 18.0
• Tutorials 18.0

ECTS 2.5

## Goal(s)

Numerical solutions of Partial Differential Equations are at the center of computational science. The object of this course is to present the main standard PDEs and to give the principles of the finite difference method. Every chapter contains the continuous problem and several discrete algorithms.
