Warning in ADS Layout

Hello All, please help
When I try to simulate filter that ports are on the line, please look at the picture, ADS give me warning and results are bad.

Warning is:

IF THE GEOMETRY CONTAINS LINES THAT ARE WITHIN 1 DEGREE OF PARALLEL THEY WILL BE TREATED AS PARALLEL BECAUSE THE LAYOUT RESOLUTION IS REALITIVELY COARSE FOR THIS GEOMETRY. PLEASE INCREASE THE LAYOUT RESOLUTION IF THIS CAUSES PROBLEM.

Yes, it causes problem. I can"t find how to icrease resolution. Where is it in ADS to change?
Maybe answer is simple but i'm begginer at ADS layout. Please help thank before.

Hi

When you setup the mesh in Momentum(Momentum -> mesh -> setup) you can specify the resolution of the mesh.

And why is a problem if parallel lines are treated as parallel ?

Hi, i made an attempt to increase the mesh frequency and cells/wavelength but it haven't solved problem.
