hi,

I am working on a project in which i have to design a model of specific length and width for heat transfer .During modeling i made length and width dimensionless to find mean bulk temperature and wall temperature after that i will find out Nusselt number from this information.

But why we use dimensionless lengths and widths in comsol modeling?
