Elmer

Introduction

Elmer is an open source (GPL) computational tool for multi-physics problems. It is developed by CSC in collaboration with Finnish universities, research laboratories and industry. To test ONELAB models working with Elmer, you shall need a working installation of the code. The easiest way to do so, is to install the generic ONELAB virtual machine on your system by following these instructions. The OLVM Virtual machine is distributed with Gmsh and Elmer preinstalled.

When done, log in into the virtual machine (username: olvm, passwd: olvm) and proceed by downloading benchmark ONELAB models.

• You have to be online.
• Open a terminal.
• Issue the command getElmerModels.sh -test at the prompt. The model examples detailed in the next section are then downloaded in the directory ELMERMODELS.
• The option -test asks for an automatic check on the downloaded models, which are solved immediately after being downloaded. The result the check is given in the file ELMERMODELS/report.txt.
