Surface Wrapping Technology
Surface Wrapping Technology Rapidly create fluid domain geometry in just a matter of seconds. NX CAE includes powerful surface wrapping technology that rapidly extracts complex interior or exterior surface volumes for CFD analysis. Furthermore, the new fluid domain geometry is associated to the base design, so you can quickly update your analysis model whenever the design changes.
