JEC Group have brought together the international community of composites leaders and executives in our Composites Circle as an unique networking opportunity to meet with both peers and future partners.
e-Xstream announced on the 4th of April 2011 the release of Digimat 4.1.2, a nonlinear multi-scale material & structure modeling platform focused on bringing new insight into composite material simulation.
Driven by delivering at every release major improvements in composite simulation, Digimat 4.1.2 focuses even further on the stabilization of computational convergence. Digimat 4.1.2 offers to the user today a new technology and standard settings that showed both robustness and efficiency on our customers’ cases especially for explicit analysis.
The new technology can be combined with stiffness update delay (SUD), a value of SUD = 2-10 saving up to 60 - 90% of CPU time with respect to SUD = 0. By combining SUD with element deletion the onset of failure can be investigated. For the investigation of post-failure behavior it is recommended to use SUD = 0.
