How do I model and solve the pde for pressure distribution as given in the figure. Everything apart from pressure will be given a numerical value. I have uploaded the model, I need to find the pressure distribution on the thrust pad bearings.

How is "H" given ? As a matrix of values - evaluated on a specified r-theta - grid ?

P = pressure
r = pad radius
theta = pad sector angle
mu = Lubricant viscosity
U = tangential Velocity
H = Lubricant film thickness

Additionally, you can refer to the following MathWorks documentation that gives a detailed description of how you can solve a partial differential equation(PDE) using MATLAB.
