Flow visualization and field line advection in computational fluid dynamics: Application to magnetic fields and turbulent flows

Mostrar todas las versiones(3)

Accurately interpreting three dimensional (3D) vector quantities output as solutions to high-resolution computational fluid dynamics (CFD) simulations can be an arduous, time-consuming task. Scientific visualization of these fields can be a powerful aid in their understanding. However, numerous pitf...
