temperature dependent heat flux

[maxxel123]

Dear members,

I hope you can help me with my question:

How can I define a temperature dependent body heat flux, i.e. a heat flux that changes with a temperature function that can be defined during a step? Is it possible to use a tabular form? Or is an if-condition feasible?

An amplitude can only be defined in dependency upon time, am I right?

Thank you so much in advance.

Best regards,
maxxel

I have been through the same. It is possible to set temperature dependant heat flux using subroutine called DFLUX. Could you please inform what are you trying to do?

thanks for your reply.

I am examining a cell of a battery and which electrical loss causing heat changes with the temperature. Could you perhaps submit such a DFLUX file if available. thanks.
