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
