Thanks for the reply. The surfaces I generated is created from the Fsubsurface feature where I give four surface edges and the parent surface, and it will return me a four edge parametrized surface, ready for meshing. Hence, I dont have control over how the surface can be parametrized differently.
If you look at the attached images. I have a wing that is connected to a fuselage. At the intersection where the wing is attached to the fuselage, the wing and the fuselage joint patches have same mapping factor, so their boundaries edges will be aligned. However, if you look at the surface in front of the fuselage joint patch, I need to manually tweak the mapping factor (-0.7) so that I can have smooth transition in the size of the mesh from the fuselage joint to the fuselage nose.
It would be great if I can know for example, given the length and the width of a patch, and also number of panels in the u and v direction, what mapping factor I need to give so that I can make sure the size the mesh at the boundary of two neighboring patch, will have similar length and width, or aspect ratio.
Again, if I simply set the distribution to be uniform, this won't be a problem, but if I want to have non-uniform distribution, I will probably need the equation in order to know what would be the right mapping factor to put in.
Please let me know if you have any suggestion. And If it is not of too much trouble, could you help ask the developer to look for the equation ? If it is too hard to find, I guess I can create a simple rectangular patch and try to reverse engineering the equation on it.
