I was actually mistaken, this is not for a modal dynamics step but rather a random response. So unfortunately I don't see the interval option in the step settings.
I checked the documentation for random response and it does appear that it uses the extracted natural frequencies to compute the...
I'm performing a modal dynamics analysis in Abaqus with the requisite frequency step beforehand. Both steps are set to 1-4000Hz. The first mode isn't found until ~90 Hz and when I plot either total or spatial acceleration from the modal dynamics step for a node anywhere on the geometry, I'm only...
