Hi all,

 I am doing a parametric analysis for different speeds of a motor from 2000 to 3000 rpm. The simulation is completed without any issues, but when I export the harmonic forces as shown in the figure below not all the forces corresponding to the different speeds are contained in the exported file. So when I import the file in ansys mechanical, I can only see the data for 4 speeds are included. How can I solve this?

Table with the different speeds 

Export harmonic force options

Speeds that are actually imported in ansys mechanical

I attach the file with the harmonic force data that is generated and imported in ansys mechanical.https://drive.google.com/file/d/1T9nkCxn_bDbrPYECqL6WWquBuiRPlolL/view?usp=sharing

Hello,

Check the analysis settings to confirm that each load step corresponds to the different speeds you're interested in and that the frequency range is correctly defined for each step.
