frequency analysis

Question asked by Nitish Kumar on Oct 30, 2015

Hi I was using solid works for frequency analysis, a cylindrical beam with area 78.5 sq mm and length 200mm fixed at one end. the results show two close natural frequencies, I am pretty sure that it is not true because the same model in matlab is yielding no close results. They are quite distinct

 

Frequency(Hertz)

in solid works                              in matlab

182.76                                            182.5

182.78                                             1135

1135.8                                             3139

1135.9    

3139      

3139.4    

 

how should I understand the results from solid works? can any one please explain.
