I'm having a problem and I don't know how to go around it. I'm trying to solve the equation (du/dt)+(du/dx)+(dP/dx)=(d2u/dx^2) using the coefficient form PDE maths physics.I used u as my dependent variable. but P is also another dependent variable here and I'm not able to define it in the physics setting because its unit is different from u. How do I define P as a variable? I tried to define it as a global variable but I don't have data on how P changes with x and don't know how P depends on x. Any help? Thank you.
