Hi! This is my weavy surface that is I created in Grasshopper with Heteroptera Attractor:
But the waves on the surface should slowly disappear towards the edges. I tried but I couldn’t do this 
This is my base surface:
This is my algrorithm:

Thanks in advance for your helps 
Multiply your Motion vector by a function of distance from the boundary like this

Oh, much much thanks! I didn’t know this method. One litte question too: How can I change where the transition between wavy surface and flat surface starts? I saw changing the graph mapper you put is working very well after remapping. Like this:
If there is a better way please enlighten me.
I tried with “MIN” first but it didn’t work (I don’t know why, I would be very happy if you enlighten me )
I have nice surface now thanks to you (I can’t figure out what is that color changing on surface but I think it not an important thing. There is no problem with its UV curves.):
Thanks 
This number controls the distance, the points not in the range will get no effect from the values of the graph mapper.
Let’s say you input 20 to the Minimum component. That means all the points out of range 20 become 20. For example, the point in the middle of the surface which has a distance of 25 from the border becomes 20, not 25.
But because the graph mapper only wants to calculate the data within the range 5(the red circle in my pic. your pic is 5, mine is 20) and make every input value beyond five one, your final result will be not changed. 20 or 25 will get the same cold reaction from the Graph Mapper because they are both out of the range it is looking for.
Oh, I got it! Thank you so much Quan Li
