Yes, the model was done in static structural. But I got two natural frequencies, not six. Here is the data of frequencies -

Could you kindly tell me why I am not getting the first six natural frequencies? Is it a problem with my engineering data or my model?  I did not get any errors. but I got a warning.  And one value is zero and the other one is 0.047 which is also close to zero.
