And then, unsteady simulations may become unavoidable. In this lifehack, we give an overview of the procedure for classic URANS simulations. We will look at the domain scaling approach and explain the most important expert parameters. Attention, there are a few differences in setting up the simulation with Fine Turbo and FINE Open.    <\/p>\n\n\n\n<figure class=\"wp-block-embed is-type-video is-provider-youtube
