Am using Eulerian Method for analyzing the segregation of sand granules in water in a jar under the action of centrifugal force. i have got results for the default properties, now i want to change the viscosity of fluid only.
My question is can i change the viscosity of fluid linearly with respect to time/temperature in fluent. please help me.... |

Yes, you can, through udf, and you can interpret it instead of compiling.
Search in google for "DEFINE_PROPERTY" macro, there are a lot of example. If you want to have a function of time you will have to use "CURRENT_TIME" in your udf; if you want to use temperature use C_T(cell,thread). Daniele |
