Help- Flow Along Multiple Curved Trimmed Surfaces

I want to flow along srf the 4 curved surfaces of my object. I’ve rebuilt the object to reduce the amount of surfaces but i don’t know how how to reduce it anymore to get flow along srf to create a seamless facade. tried looking at other forum posts here but nothing is working. if the solution requires grasshopper just know i really don’t know much of grasshopper.
