Hi
You can geerate several types of higher order cures in COMSOL, at least rather easily in 2D by creating a Bezier curve and then editing it (double click on the curve). If you have a surface, decompose it first ("coerce to curve") and "slpit" it to elementary items, and delete unwanted items. Then play with the weight value. sqrt(2) gives a circle.
You have als the "higher" order curves.
Take a look in the documentation for the full formulas or select a good mathematics book on Bezier curves
Good luck
