Re: Transient Thermal Simulation with small slots for air flow.
Ryan Dark Jun 26, 2018 1:46 PM (in response to Hao Tang)Hi Hao,
If you are using Flow Simulation the act of cutting these slots should allow for the airflow to release the hot gas and keep the system at a "true to life" temperature. If you are trying to analyze this system with Thermal Simulation then you would need to adjust the convection constants for all interior faces to accommodate natural convection off all internal surfaces. For Thermal Simulation this would be a somewhat complex calculation to find the appropriate convection constant.
These are just general suggestions. If you post the model or images of the model and the study/project setup we can all probably take a look and offer some better advice.

Re: Transient Thermal Simulation with small slots for air flow.
Hao Tang Jul 11, 2018 3:59 PM (in response to Ryan Dark)Thanks for the reply Ryan. I am able to create a variable convection coefficient and external atmospheric temperatures wrt time so I got that covered in the Thermal Simulation. However, If I create holes that expose the interior of the box, would applying a convection coefficient in the hole allow the cold air to come into the box and would that be able to factor in the temperature due to convection through that hole?
Thanks,
Hao

Thermal study in Simulation is not able to account for the change in bulk ambient temperatures of the fluid around your model in the way you are describing. There is not a way to account for the cooling effect of having holes vent the inside to the outside. This would require the use of Flow Simulation or some kind of CFD analysis tool instead.
