Hi All!
do someone know what does the following warning mean?

port nn : mesher chose to use an analytical (approximating) formula to estimate the wavelength it needs to determine the maximum cellsize

Thanks

This message means that the 2D port solver was not able to compute a phase constant and therefore no wavelength for the port. The analytical approach takes into account the frequency and local dielectric properties and is good enough for meshing.

Thank!
but the simulation results are still accurate?

Simulation results are not affected as they are going to be normalized to the impedance you chose and/or to 50 Ohms. Only the S_Z0 array in the dataset will be set to 50 Ohms since Z0 cannot be computed.
