Sorry. I am poor at English.
There is a Flow Strainer grid inside the duct.
The grid spacing is 39x39 [mm].
How is the Porous Condition in Flow Simulation?
Please give detailed explanation.
You can use Flow Simulation to calculate the properties for a porous media based on the geometry of that grate. It is described in this video (GoEngineer - Flow Simulation: Calculate Porous Media Properties) starting at 10:45. The video goes through how to setup the project to find the properties as well as how to then put those properties back into the Engineering Database for Flow Simulation in order to use it as a porous media.
