ABAQUS SSD, Modal gab in the frequence range

[Nico144]

Hello,

I would like to have my frame for my analysis with a constant increment (every Hz). But for the moment I have a big gap between 400 and 600 Hz.
Do you know what modif I should do in my step or fieldoutput to get this result?

Thanks

You can add multi frequency ranges and increase the number of computation points while lowering the bias. This will create more results in the range.
An enforcement for 1Hz intervals is only indirect possible. But usually it makes no sense, since it is not much going on away from the eigenfrequencies and only takes computational resources.
