Dear Robin,

Please go through attached matlab code, where in I have mentioned two codes.

First code gives curl of three sides of triangle for which solution is a constant.

Second code gives curl of a custom profile for which solution is in terms of x and  y.

Could you please explain the difference.

Thanks
