Hello All,
I am working on transient conjugate heat transfer in which solid material properties are changing with time which are thermal conductivity and temperature. Is it possible to change properties with time in fluent 14.5 or can we can use piece wise polynomial ?? |

A temperature dependent conductivity is straightforward to implement which would be an implicit function of time. Built-in, Fluent will let you define polynomial functions of temperature for material properties.
Are you asking specifically about material properties that are explicitly time-dependent? Time-dependent material properties are a questionable approach but this can be done with a user-defined function. |
