Kangaroo surface inflection paperlike

Hi Everyone

I'm trying to simulate a surface inflection like in the image below

I tried a simple definition that I found in the forum and adjusted it with kangaroo collide surf component to simulate the applied pressure

but:

1. the mesh comes out very edgy and behaves more like fabric than parer

while I need it as stiff as the paper model

2.another problem is that when I move around the collision brep the surface suddenly tears apart

any ideas to any of these problems?

also please refer to the attached definition- maybe I'm missing any important settings?

thanks in advance for help!
