Form-Finding Capabilites
ixForten 4000 form-finder is able to relax a mesh into a shape with
assigned prestress and/or tension. Not only the membrane can be specified but also
the supporting steel,wood or concrete framework. The system uses a range of
technologies to produce the final result based in a “self stressed” model. Membrane
stress state, cable tension, beam bending moments and stiff plates a part of this
global equilibrated system.
ixForten 4000 has a number of Form-finding streategies for this purpose:
Linear FDM : Linear Force Density method controlled by the force density value
C. The mesh is relaxed and all links end up with a positive tension proportional to the
C value.
Non-Linear FDM : Non linear force density method enables constraints like fixed
force, fixed length and fixed unstrained length on the links.
Brute Force FDM : The Brute force FDM solver enables fixed force and fixed
length links using a sparse matrix solve technology that outperforms hundred of times
the speed on the classic Non-Linear FDM solver.
URM Solver: The Update Reference Strategy is a technique developed by prof.
Bletzinger and enables direct form-finding over triangle and quad meshes. IsoTropic
or Anisotropic membrane stress state can be specified and so natural minimal
surfaces are easily shaped with this technology.
