[Maxima] Navier-Stokes equations and itensor package.

[Grigory Sarnitskiy]

Hello, I want to be able to deal with NS or RANS equations with Maxima --- symbolically sum them, multiply by some functions in order to obtain new sets of equations. As far as I understand I need to employ itensor package, but there are no tutorials to help.

Could any one show me how to write next equations in Maxima?
