shock wave in water
Hi all,
Does anybody have any experience with simulating water as an compressible liquid in fluent? I have already written an udf file for relation between density and pressure. But since I want to use the explicit solver (because Fluent help says that this solver is better for capturing shock), when I use it I get this error: "global time stepping cannot be used for incompressible flow" however I have changed the material to water and the density and speed of sound to udf. I think this should be enough for fluent to realize that I am solving compressible flow. Anybody has any idea how to get rid of this error? |

Make sure you are using the explicit density based solver (regardless of how you use UDFs to take care of everything else). |
Thanks for your reply. I use explicit solver (density-based) with a udf for water density. But still have the same error. it seems fluent cannot realize the udf. I guess the only EOS fluent supports with explicit solver is "Ideal gas".
has anybody simulated water as compressible with explicit solver? |
