You might also be interested in trying the inflation tools in Kangaroo:

There is an example included in this zip:

It should work with any mesh, provided it is reasonably nicely triangulated

Comment by Roberto Maffei on May 9, 2011 at 3:10am: dear, thanks for the help! it work quite well. any news about the imperfection (expansion below the xy plane?)

I'm using Forten or Easy to solve the form finding more precisely but at the moment I'm investigation what gh can do! for example i would like to inflate more complex shapes. i'm trying with a sort cylinder (loft btw a circle and an ellipse). Unfortunately i don't know how to share my definition with you, but here in the pic you can see how the mesh collapses

Comment by Jon Mirtschin on May 6, 2011 at 5:48am: Hi Roberto,

I'm assuming you want the mesh vertex welded, Weaverbird has a component for this.

The result is probably close to the result you need, get the definition here.

I will take a look at why it expands below the XY Plane, more accurate results can be obtained using a commercial solver such as Oasys GSA (including material stiffness representation)

I'l looking into the inflation tool you've done! it is great! unfortunately i have some problems to inflate some brep or other shapes. for example here you see what happen with a cyilinder. it seems it brakes the mesh. is there an option to keep it close?

thanks a lot!

Comment by Jon Mirtschin on May 16, 2010 at 7:44am: Hey Wieland,

Yes, I'm supporting both versions for the time being. I'm just building the plug-in now and uploading the sample definition for users to try out. So check it within an hour or so.
