Coupled thermal/fluid analysis

Duration: 4 Days


With NX Thermal / Flow tasks of fluid mechanics, complex thermal problems and coupled thermal / fluid tasks can be solved. This is realized by each one solver for thermal and one for fluid mechanics calculations which can be coupled, if necessary. In this seminar we discuss the methodology for the couplings between the fluid mechanical and thermal solver.
