is a specialized engineering platform developed by ixRay.ltd for the design, structural analysis, and manufacturing of tensile membrane structures . These structures—ranging from stadium roofs and airport hangars to smaller architectural umbrellas—rely on fabric and cable systems that stay in place through tension rather than traditional rigid bending.
One of its standout features is the direct connection to CFD applications. This allows engineers to simulate wind behavior over a membrane surface to calculate precise pressure (Cp) values. ixforten 4000
The software is known for its ability to handle non-linear geometric analysis, which is essential because fabric structures change shape significantly under load (like wind or snow). is a specialized engineering platform developed by ixRay
It utilizes the Force Density Method (FDM) , which allows designers to find the optimal shape for a membrane by balancing cable forces and surface tension. This allows engineers to simulate wind behavior over
For years, ixForten 4000 served as a core tool for engineers to perform "form-finding," a process where the software determines the natural equilibrium shape of a fabric surface under tension.
