When i add port i have 2 options. First one is porous material and second one is rigid object. First i choosed rigid object and it worked and gave me a results like Erik's. There is a huge numbers of coifficent it didn't reduce just increased. After that i selected porous metarial and i had an error it said 'The input power at the driven port is equal to zero. Please check the port definitions.'

So is this analyze true or not?

I think i did a mistake but i couldn't realize it.

 

 

This is when i choosed rigid object port surface
