Hi Weiqiang,


The surface-to-volume ratio as shown in the your post is for surface reaction instead of thermal purpose so that it appears under the reaction tab. For more details, you can refer to the theory guide: https://ansyshelp.ansys.com/account/secured?returnurl=/Views/Secured/corp/v202/en/flu_th/flu_th_sec_species_surface_bc.html?q=surface-to-volume%20ratio


Thanks.
