hfss model dimensions

Building model have the following the warning,

[warning] Model dimensions are beyond the range of 1e-006 to 10000

I want to ask that it will affect the result???

and how to avoid the warning.

thanks!!!

another question:

[warning] Warning - Boundary 'Rad1', Boundary 'WavePort1' : Boundaries overlap.

This warning will affect the results???

thanks!!!

Model dimensions should be in the region 1e-006 to 10000 of your current default units.For example if the default length units are mm model dimensions should not be less than 1e-006mm or larger than 10000mm.So i suggest that you change default length units(tools->options->general options->default units).As far as the boundary is concerned check boundary display(solver view) in hfss menu.If both boundaries are visible to solver then since ports have the highest priority things should be ok.

Hello :

I don't know what is your stracture , but if your stracture is an antenna and you draw a radiation box for it , you should know :

the massage "[warning] Warning - Boundary 'Rad1', Boundary 'WavePort1' : Boundaries overlap. " usaully appears when you chooses your feeding port in the radiation box so you should choose it out of the radiation box .

good luck

Hi si_green.
The massage "[warning] Warning - Boundary 'Rad1', Boundary 'WavePort1' : Boundaries overlap. " not affects return loss and radiation paterns, beacuse HFSS asume it WavePort automatically. But I believe that if you use lumped port (if your structure accepts it), radiation blockage of port can be reduced.
