Hi

I create a simple TL in schematic and simulate its S-params, the result is a resonant in 3GHz and it's definitely  match with theory.
I transfer the design to Momentum and simulate that the odd results are
1.5GHz resonance for Mesh Density of 20
1.1GHz resonance for Mesh Density of 30
800MHz resonance for Mesh Density of 50

when I switch from Momentum to Momentum RF I have better results

2.4GHz resonance for Mesh Density of 20
2GHz resonance for Mesh Density of 30

if I enable the Edge mesh results are worse.(I have lower resonance Freqs)
I set the Simulation to Adaptive and it simulates always 7 points.

Regards.
