Hello guys,
as the name of the topic says, I would like to kindly ask you for your help. I want to imitate mambrane shape by using soap film in kangaroo. I think Im quite there but I have problem with the softness of resulting surface. How can I make it softer? Any help or ideas is appreciated, files attached. Thank you in advance!

When relaxing a mesh, it is important that the mesh you create before feeding it into Kangaroo has nice triangles (the closer to even sizes and equal angles the better).
I tweaked the mesh settings to improve this, and also added some zero length springs for the edges. The soap-film goal on its own can be a bit tricky to work with - since it has no in-plane stiffness. If you aren’t seeking exactly zero mean curvature, but just want a tensile membrane surface, then it is much easier to use zero length springs.

Firstly, Thank you!
I’m not sure why, but your file didn’t worked for me. Every time I tried to relax shape, surface disappeared. And mesh was also completely broken. I refined it but with no luck to get relaxed surface by kangaroo solver.
Anyways, your points were valid, so I was able to refine the mesh and the surface. I still get some small fragments at the shorter edge but I will try to correct it later. Its because the triangles get a bit deformed after relaxation.
File is attached.
