I have to solve four nos. of equations with 5 nos. of unknown variables, two of these equations contains second order partial differentiation equation and two of them having first order partial differentiation equations. I don't know how to solve these equations and get the solutions of these variables ?
Dear Ajay Sharma ,
In EES solving a partial differential equation, need to define the time step
Satrt _time , end_time, initial boundary conditions. The method relied upon the finite difference method to calculate the T2.
best regards

I think it would be helpful If you have shown us the system of differential equations you want to solve.
Mathematica is a really good software for this type of problems. You can even try their AI website for free for problem resolution.
