Trouble creating Erosion on set of contoured layers

Hi everyone,

I've been attempting to achieve a natural process of erosion through Grasshopper by taking a look at this:

However, I've been having a trouble composing the definition together as it doesn't seem to be working... I offsetted the surfaces from a bunch of contours I did from Kangaroo, however I think it's not working since I think the brep layers are empty? I really am not sure though and any help with this would be unreal, as I am not achieving any erosion effect!

Here's the form I am trying to attempt to demonstrate erosion

Kind regards,

"Brep layers"?

Upload a working example please, nobody can say anything useful about any problems in your file just by looking at the result.

Hey David,

So sorry about that, I was uploading the rhino + grasshopper file but I must've submitted before it fully uploaded. I ended up getting somewhat of a similar result, however the bottom layers go funny after the 'erosion' values become too high... its to do with the direction of the interior curved lines and I'm stuck on what to do...

ah bugger, didn't upload successively again. Here's my grasshopper file (with the rhino data internalized). Is there any way i can change the directio of the interior circles' curves?
