Run the first Elmer analysis

To run your first analysis, just open an Elmer environment terminal by double-clicking the desktop shortcut created using this guide for quick access:

Elmer desktop icon

The command prompt window will open:

cmd Elmer terminal

Move to the tutorial folder:

Elmer console:
cd tutorialCase

The Rayleigh-Bénard simulation folder contains three files:

  • ELMERSOLVER_STARTINFO
  • conveRB.sif
  • conveRB.grd

First of all, you need to create the mesh. The input file that contains all the information is conveRB.grd, while the application that has to be run is ElmerGrid.
In the command line, simply run:

Elmer console:
ElmerGrid 1 2 conveRB.grd -out Mesh

Instantly the Mesh folder will appear. The image below shows the mesh displayed in paraView.

Now you are ready to launch ElmeSolver to run the analysis:

Elmer console:
ElmerSolver

Once this is done the simulation will start:

Elmer run
