I think I would only need to be able to replace the variables and also the derivative operators (as in a change of variables $\hat{x}=x/L$), grouping the dimensionless numbers can be done by hand.
It is a similar procedure to what is being done here: (en.wikipedia.org/wiki/Non-dimensionalization_and_scaling_of_the_Navier%E2%80%93Stokes_equations) . I was wondering if this can be done with SAGE.salazardetroyaWed, 20 Apr 2022 06:20:22 +0200https://ask.sagemath.org/question/62056/Gradient, Divergence, Curl and vector productshttps://ask.sagemath.org/question/10104/gradient-divergence-curl-and-vector-products/Are there implementations of vector product and the nabla operator yet? I can't find anything.KiMon, 21 Oct 2013 12:40:22 +0200https://ask.sagemath.org/question/10104/
