Many structures repeast around an axis (i.e. fans, turbines). For these structures, NFX 2015 can pattern geometries and loads cyclically, so you only need to model one small section to evaluate the behavior of the whole structure
This function helps to analyze flow, heat, and mass transport in complex pipe networks easily with great saving of computational time. Try how to create 1D CFD element and how to connect it with 3D domain
Inertia relief enables the analysis of unsupported systems such as automotives in motion, or satellites in space. It releases the inertia effect and the relative displacements are independent of constraint conditions.
