Mass imbalance fluent

Web2 de nov. de 2016 · By default, Fluent only exposes mass-imbalance (related to continuity residual) to the user. When post-processing, this can be found in the Residuals group of variables. To access the other residuals, you need to enable a certain expert parameter prior to solving. Expert parameters can be accessed using the TUI command ‘ /solve/set/expert ’. Webmuchong.com

WebSolid is initially patched within part of the bottom area with volume fraction of 0.55. The problem is that, the total mass of solid phase keeps dropping, with the solid mass flow rates of all the boundaries to be 0. Since I use constant density, the total volume of solid phase is dropping in the same way, while volume of gas phase is increasing. http://cfluid.com/forum.php?mod=viewthread&tid=126297 tarot mundijeux https://theyocumfamily.com
