Resonance Freq1 = 84.36

Resonance Freq2 =528.84

Resonance Freq3 =949.31

Resonance Freq4 =1316.00

Resonance Freq5 =1481.41

Resonance Freq6 =2882.00

But Euler beam theory (options>>constants) gives me the following

Resonance Freq1 = 84.36

Resonance Freq2 =528.66

Resonance Freq3 =1862.89

Resonance Freq4 =3650.55

Resonance Freq5 =6034.61

Resonance Freq6 =9064.89

Clearly the results do not match after 2nd natural/ resonance freq. I am quite sure that COMSOL example model cannot be wrong but there is something odd. Some elaboration would be appreciated
