[boundary condition] Temperature jump

DashaSh · January 9, 2024, 10:10

Dear All,

Is it possible to set the inlet temperature "jump" depending on the average outlet temperature without using the cyclic patch condition?

In my problem, the inlet temperature heats up over time and I would like to set such a condition, similar to the existing jumpTable, but without using cyclic for existing patches, since it is important for me to preserve the calculation of the inlet and outlet flow, and only the temperature will change. Can someone tell me how this can be done?

Hi Dasha,

It looks like you would want the outletMappedUniformInletHeatAddition/

Best regards,

Tom

Thanks, this is a good option, but I haven't tested it.

If it will be useful to someone in the future, I found a solution to this problem using codedFixedValue and this post
