Dear all,
I am working in solid part and trying to get Eigen frequency for a cylinder.I need to get frequency in weather,water and in oil.when i use sweep in a special range of frequencies the result is strange,because when i change the step of frequency the results is difference.for Ex:when step of Frequency is 300 Hz the results in weather,water and oil is difference that is logical.but when i change the step to 100 Hz the results in weather,water and oil is same!!and I don't know that i should change my physics or another...
please help me.
