In this work one approach for formfinding and analysing tension membrane
structures is described. Focus has been on the conceptual stage. For this the computer
software SMART Form has been further developed, enabling the possibility to do real-time
formfinding and analysis of fabric structures. The software is based on a method where the
orthotropic membrane is modeled with a triangular mesh, where the mass is lumped on the
nodes. As a computational tool dynamic relaxation is used to find the static equilibrium
configuration for the structure. The advantage with this is that there is no need for formulation
and manipulation of matrices common in the finite element method
