Hi, everyone

I wonder - if there is a way to use derivative with respect to time of a variable? - say, Temperature or Passive Scalar;
to be more precise i want to use a Source Term that looks like
Const * dTemperature/dTime

I will be grateful for help - 'cause i'm stuck :>

Create a Field History monitor, which creates fields for the last n number of timesteps for the variable. Then you can define a time-deriative using your own temporal discretization scheme. There is an example in the user guide for creating a time derivative using Field Histories
