hfss question

hello ,

I have an hfss problem. While the simulations work perfectly , sometimes I get , when I ask for a graphical result , like for exemple db(s11) one or two points in the frequency domain show a completely wrong result. I got this on several differents simulations , and I dont know how to cure it.
I feel that it is a simulation problem , not a real world result. Any idea?

hfss question

It might be a spurious numerical error, especially if it occurs randomly at different frequencies. If so, increasing the mesh density might solve the problem.
