AMDiS-Workshop

AMDIS - WORKSHOP

Introduction to the finite-element software AMDiS

The workshop provides an introduction to the finite-element software AMDiS, developed at the institut for scientific computing at TU-Dresden. The goal for this workhsop is, that the participants learn how to use the framework to solve partial differential equations from simple up to complex problems, to implement stationary and instationary problems in 1d, 2d and 3d, to handle complex geometries, curved surfaces, adaptive grids and to run the simulation sequentially and in parallel. Furthermore, the participants get an overview about advanced topics, regarding meshconstruction/-conversion using meshconv, the multi-mesh approach, error-estimators and the handling of coupled physical problems.

Modul

The workshop is part of the lecture module Math Ma WIA and thus creditable for students. A certificate can be provided for participants who work on a project introduced at the beginning of the workshop. The results should be presented at the end of the week. These projects can be solved using the information from the introductory courses of the workshop.
