Default Time-varying heat transfert coefficient (htc) with externalWallHeatFluxTemperature BC

Hello everyone,

I am trying to set up the boundary condition externalWallHeatFluxTemperature in coefficient mode as follows :


type externalWallHeatFluxTemperature;
mode coefficient;
Ta constant 300.0;
h constant 10.0;

kappaMethod fluidThermo;
value uniform 400;


It works like this.

In my research I managed to set up Ta from a data table (time dependent), but I would like to go further and set up the heat transfer coefficient (bold line in code) as a time dependent variable which will be defined from a data table.

After some research[1], I know that Ta is defined as a Function1 type but h is defined as a patchFunction1 type and I don't know how I can set up the value of a patchFunction1 variable from a data table (even if I know it is possible).


Please, could you help me setting up this condition ?

Thank you in advance,

I am trying to do a similar thing. I want to specify time-varying heat flux condition with externalWallHeatFluxTemperature BC. Did you find a solution to your problem?
