I am new to Maple, bit I am getting familiar with it. My current interest is in Lie Symmetry analysis of systems of PDE's such as mass, momentum, and energy balance equations in fluid dynamics, for example.
I have carried out a Lie Symmetry analysis for a single PDE's -- attached herewith. I know it to be correct because it is already published. What I want to do now is how to write down more than 1 PDE's and carry out a similar Lie Symmetry analysis to this system of PDE's. I have been unable to find an example on the web.
Can you advise please - especially how to enter a systems of PDE's as apposed to just one PDE.
