Is it possible to get matlab to do a symbolic integration of a gradient where you know that each term is dependent only on one variable?
I'm trying to get Matlab to do the following:
syms P(r,z) rho g omega P_atm
ode1 = diff(P,z) == rho * g
ode2 = diff(P,r) == rho * omega^2 / r
ode_total = ode1 + ode2
cond = P(0,0) = P_atm
soln(r,z) = dsolve(ode_total, cond);
Essentially, I'm trying to do the following:
Given the following pressure gradient in two dimensions (or three, where ), solve for the pressure as a function of r and z [and θ]: , using the relation: and boundary condition:
How do I code the above process to result in the following solution (or is it even possible)?
As you might have guessed, these equations are derived from navier-stokes.
