How to define an energy source based on measuring a point monitor

      I am running a Fluent simulation of a fan oven. I am trying to control the energy source term of the heater using an expression where I switch it on and off when the setpoint of a point monitor (much like the thermocouple in the oven) is reached. However I'm not sure how to correctly implement this. I cannot use a report definition in the expression as per error message below. Any advice? Thank you.

      Hello Have you created a report definition to monitor the temperature at the specified point? Is this what you are using here?
      The note about the plot is simply saying that Fluent does not have the data to plot this expression. I do not think you need to worry about this.

      Hi Karthik Thank you for your reply. Yes the {point} is a vertex average at a defined coordinate point as below:

      I try and enter the expression in the cell zone but I get the following error and it wont let me select it.

      What do you think?
      Kind regards Sean
