How to get the average heat flux at a surface in Simulate thermal analysis similar to Fluent?

Good morning, warriors still using Simulate, 

 

I just finished a thermal analysis and obtained nice plots of temperature profile and heat flux profile. Since the heat flux at one contacting surface is not uniform, it is difficult to calculate the heat flow power through that surface.

 

Is there a way now in Simulate to get the average heat flow power at a surface. I know Fluent has it, because I have been using it in another simulation job (for a different company. Note: I am working concurrently for different employers).

 

Thanks for any hints.

 

Best regards.

In Simulate, select Measures, then follow the sequence of actions: New\Type a name\Select Heat Transfer Rate under Quantity group\Select any surface such as the mounting surface.

 

After the thermal simulation is done (note: have to select FLUX in Output setup), open the result and select Measures under Report group.

Interface Flux Results Quantity
 
Creo Simulate supports this quantity for all Thermal models in the native mode. The Interface Flux reports maximum flux of heat through the thermal resistance interface. Creo Simulate calculates the Interface Flux quantity for thermal analyses, when you define the Thermal Resistance interface in your model and select Heat Flux as an output of the analysis.
When you select the Interface Flux as the Quantity and Graph as your Display type, Creo Simulate displays Interface Flux as the graph ordinate. You can select graph abscissa from the Quantity tab. Creo Simulate adds the Graph Location selection to the Quantity tab. Use the associated selector arrow to display your model and pick the entity you want to use in your results display.
Return to Quantity for Result Windows or To Define a Interface Flux Results Quantity.

    Thanks for prompt reply.

     

    The "surface" in concern is the mounting surface where the total heat flow power is the primary concern. Right now a prescribed temperature is applied on this surface. 

     

    It looks like that I need to add one more dummy part to form the "interface" and assign a thermal contact resistance value to it. The prescribed temperature will then be assigned to the dummy part. I am to setup and have a test run.

     

    Thanks for the hint.
