Solving PDEs with mixed derivatives

Suppose I have an equation of the form:

Can I use pdepe to solve that equation as is, or do I have to do a co-ordinate transformation first to get rid of the mixed derivative?

Hi,
I understand you want to use “pdepe” to solve PDE with mixed derivatives.
“pdepe” is normally used to solve 1-D parabolic and elliptic PDEs and not for mixed derivatives.
I would suggest you to go through the below documentation to understand when to use “pdepe” for solving PDE’s.
I hope it helps.
Thanks!!
