How can I solve non-dimensional equations in FOAM -- CFD Online Discussion Forums

mcgintygs New Member Sean McGinty Join Date: Sep 2013 Posts: 4 Rep Power: 12	I'm interested in solving (as a starting point) a non-dimensionalised version of laplacianFoam. After I have chosen my non-dimensionalisation, how can I implement this in Foam? I'm worried that foam checks dimensions! For example: How do I change the timestep and spatial coordinates (in blockMeshDict) to be non-dimensional, and how do I deal with diffusion coefficients (which will become ratios of diffusion coefficients after the non-dimensionalisation) Is it possible to do this. Does anyone know how? Any help would be much appreciated.
