NX Flow

NX™ Advanced Flow es un módulo adicional de la familia NX™ Advanced Simulation que amplía las capacidades de NX Flow y NX Electronic Systems Cooling (requiere licencia de NX Flow como pre-requisito). NX Advanced Flow es una potente herramienta para la resolución de complejos problemas de análisis de fluidos (CFD). Combinado con NX Thermal y NX Advanced Thermal permite resolver una amplia gama de problemas multifísicos de acoplamiento fluido-térmico. NX Advanced Flow simula flujos internos y externos incluyendo flujos compresibles y de alta velocidad, fluidos no Newtonianos, trayectorias de partículas pesadas, condiciones de contorno en movimiento y soporte de múltiples marcos de rotación de referencia.

NX Advanced Flow uses computational fluid dynamics (CFD) to accurately and efficiently simulate fluid flow and convection. An element-based, finite volume CFD scheme is used to compute 3D fluid velocity, temperature and pressure by solving the Navier-Stokes equations. NX Advanced Flow technology allows users to model complex fluid flow problems. NX Advanced flow is an add-on to NX Flow and NX Electronic Systems Cooling.
