WebOct 28, 2024 · Yes I did follow the reference frame tutorial, but the problem is that in my case, in the boundary condition "wall" of my solid volume (the external titanium cylinder) the momentum option is not active. So I cannot set the "wall" setting as "moving wall" instead of "stationary wall". WebThe MRF model is the simplest of the two approaches for multiple zones. It is a steady-state approximation in which individual cell zones move at different rotational and/or translational speeds. The flow in each moving cell zone is solved using the moving reference frame equations. If the zone is stationary {tex} (\omega = 0) {/tex}, the ... WebNov 24, 2010 · Some shortcuts and code optimizations are likely implemented in the stationary wall BC as compared to the moving wall with zero absolute velocity.
