Introduction
Use OpenFOAM to analyze the heating of water above sauna's oven. The problem is during the winter when the water freezes.
Other possibilities would be to create a simple Laplacian solver. but I'd like to include Navier-Stokes equations and perhaps energy equation: ice melts into water, water freezes, latent heat is released and the interfaces move.

Workflow
- Generate mesh
- For example: blockMesh
- Run solver
- Example: laplacianFoam or: buoyantSimpleFoam
- View results
- paraFoam
Use foamSearch <keyword> or find $FOAM_TUTORIALS -type f | grep <keyword> . For example: find $FOAM_TUTORIALS -type f | grep laplacian will show every diffusion example. Start with laplacianFoam → buoyantSimpleFoam → conjugate heat transfer examples.
