Magnetic field Variation from a Cylindrical shaped Permanent Magnet

Kindly help me to solve the below issue.
My model is a very simple one, consisting of a permanent magnet having a residual magnetic field, say along X direction, of 1 T. Magnet is circular in shape of radius 15mm and height 5 mm. I have a put large enclosure (around this magnet) with permeability = 1 to simulate the presence of air.
Bottom face of the Magnet is placed along XY plane, at Z = 0.
My objective is to find the X component of the magnetic field along a cross-section line formed between the points (x =-0.003, y= 0, z = -0.003) and (x =0.003, y= 0, z = -0.003))
Meshing chosen: Extra Fine, Normal; COMSOL Version: 3.4
Snapshots of the result obtained, with different meshing, is attached.
Problem: The field along the above line is different for different types of meshing.
I want to study the exact variation of field along this line.
Moreover, the field variation is not a continuous curve and has many discontinuities which are unexpected.
Is there any settings/method in COMSOL by which i can obtain a continuous and correct variation of magnetic field (along X direction) along the above line.
Thanks in Advance,
Best Regards,
Anoop
