Hello, could anyone help how to smooth the graph. I have attached the graph that is the derivative of magnetic flux density with respect to phi. I tried my best to make the graph smoother by increasing the number of mesh elements and making the recovery everywhere in the quality section of the point graph it worked alot but still its not completely smooth. The graph is attached...

derivatives have a tendency to be noisy. You can try to increase the discretization from quadratic to cubic. This helps sometimes, but of course at the price of higher memory demand and longer computation.

Cheers

Thanks kaiser, it worked but is there any other way of solving this because its taking too long and sometimes the system stuck....

You can try to reduce the mesh resolution.
