Flow along surface problem

hi all
i need your help. how to get the best results of flow along surface?

thank you so much

The following don’t apply just to Grasshopper-related topics:

thank you, am new in the forum forgive me also am asking about normal flow along surface not in Grasshopper
thanks again

the flow command works on the control point density relation between the base surface and the target surface, make sure that both have the same quantity and similar position, there you will reduce the deformation in the result.

thanks a lot Diego i will try that.
