Well ixForten 4000 has become a huge software. Its a full featured fem analysis package, patterning , 3 form-finding methods , coubled and uncoupled non-linear analysis and a lot more. The URS method of RhinoMembrane is one of the base theories and the new release will be available after i showcase it in Munich at the structural membranes conference on 9 october , keep in touch I will let you get a trial.
Still working with both of them. We have a 8-10 person studio downtown.
The GHing is well. Just recently got to take it to a new personal level where I am stringing together many smaller components to generate geometry and fab-layout all from excel coordinates. It is a work in progress though. I am a big fan of GH! Wish I could use it on everything.
I am also starting to explore some multiphysics tools to model fluid-structure interaction of flexible structures. We should grab a drink sometime.
