Dear Members,
I have a differential equation that i need to nondimensionalize.
Therefore, i introduced a new nondimensional varibles and so that i get
a nondimensional equation. I am wondering how can i do that in
Mathematica?. For example if i have this term:
K*D[v,{x,2}],
my new nondimensional variables are:
x*=x/L and v*=v/L,
I can do that by hand, but since i have a huge number of equations, i
rather prefer to use Mathematica.
I appreciate any help in this regard, and many thanks in anticipation.
