I have a question regarding the units after creating the frequency calculation and the related displacement factor.
I have a model added below. Where i create a Frequency calculation combined with static.
so just a static calculation and add the code below after the *END STEP of static to create to eignemodes calculation.
Code: Select all
*STEP, PERTURBATION
*FREQUENCY
10
*END STEP
my problem is that when plotting the eigenmodes plots the max displacement = 360 or so mm(??). while the max distance = 126.25 mm. So it breaks everything... when showing even at displacement factor 1.

I'm not sure but i would say that the resulting values aren't mm there is no input energy added so also no magnitude...
Would it be possible to scale this max value so 'large' displacements can shown normal??
