KANGAROO Pressure

I have some trouble inflating my mesh, somehow the shape doesn’t change, I did it before with a box and it works. I don’t know what I’m doing wrong

Did you mean to post a file?
The shape in your image looks inflated and like it is working.
You might want to use a higher subdivision level to get a smoother surface.

I also recommend using the Weaverbird ‘Stellate’ component with the distance set to 0 to triangulate the quad faces. This splits each quad into 4 triangles symmetrically, whereas the default triangulation can introduce a directional bias that can cause the resulting inflated form to twist in unwanted ways.

The square is inflated but the other one (the rectangular/origami mesh) isn`t inflating, remains the same shape

It helps to add a few anchor points. You need to attach it somewhere

Hi,

Here’s another great inflation example:

ETFE Cushion

Here’s a mesh inflation example using Kangaroo2: [inflation_mesh] Some mesh components from Weaverbird are also used. [17] Depending on what your end goal is, you might want to introduce some more simulation elements. A collision plane would be great to introduce some sort of ground condition. You could also add specific anchor points, where the air structure would be fastened to supports or something else. These could be fixed or movable in only some directions to get maybe more interest…
