Solidworks simulation premium, how to simulate a "sine waveform vibration" test?

A sine waveform vibration test has been done to a prototype. I want to simulate the test using the Solidworks simulation premium package.

 

Question No. 1: I did the frequency study to the model and get 23 modes in the range of 0-2000 Hz. I wanted to copy the results to a new dynamic study, but the system told me like "Frequency studies with beam mesh, inplane loading effect due to applied loads or any type of remote loading cannot be copied to dynamic studies". I don't have any like beam mesh, inplane loading or remote loading in my model. How can I address this issue?

 

Question No. 2: how to set up the simulation parameters to restore the real test which is described as the following?

                         (a) Frequency: Logarithmic Sweep from 10 Hz to 2000 Hz to 10 Hz

                         (b) Sweep Period: 20 minutes

                         (c) Displacement Limits: 1.5 mm from 10 Hz to 57.5 Hz

                         (d) Acceleration Limits: 69.3 m/sec2 RMS (10g peak) from 57.5 Hz to 2000 Hz

                         (e) Duration: 8 hours/axis

 

Any input will be highly appreciated!
