Answer 2

Frequency range in design Modeler

Answer:

The frequency range depends on the loads important to your application  

Explanation:

For instance, if the beam is a bridge that supports a car that drives through the bridge, then the weight of the car will be the load. The car drives through the bridge, then the load moves through the beam.

Another example:

Assume a three-storey building at the top with a generator (gen-set) of electricity. We know the RPM and the (from the manufacturer's spec) force produced. To obtain the individual frequencies, we can analyse the FE model. Then those with frequencies within the operating frequency of the gen-set plus or minus 20 percent are the most significant eigen modes. Consider all modes, from the lowest to the operating frequency of the gen-set, plus 20%.
