Hello everybody
I am currently designing a pneumatic formwork for a shell surface I made.
The goal right now is to get this inflatable as close as possible to the real inflated situation (in order to predict wrinkles, see which improvements I can make in order to prevent those wrinkles and thus create a good formwork). I already found a lot of information on this forum and on the internet and found a way to inflate a mesh. At least it works for a simple mesh box (I already tested that), but it does not for my shape.
My mess is -according to rhino- a bad mesh and I don’t succeed in fixing it. As you can see in one of the pictures I attached, there are way too many small parts in the red circles, but I didn’t yet find a good way to clean those up. Any suggestions?
Any tips about how to get as close as possible to the real life shape (which is not yet at the moment I think so) are welcome!
I added the rhino6 file (with the shell surface, the closed polysurface of the inflatable and the mesh of the inflatable) and my grasshopper file.
For your interest and to get a better idea of what I am doing, I included some pictures of my previous scale model
Thanks in advance!
