Hi Jousef!

I know the benefits of CSV upload, actually that’s what I use in the [definition of my loads](https://www.simscale.com/forum/t/vibration-test-given-the-displacement-amplitude/83144). However, it seems not to be availabe in the case of displacements, look at the picture, it’s the definition of my zy constraint for the base of my geometry.

I am allowed to constrain or unconstrain the displacements in any direction but, in case of a prescribed value, this MUST be 0, no chance to give another value nor even a button for CSV uploading. Actually, that’s why I defined the load in the way shown in the previous link I provided.

Anyway, it would be a very interesting point to have the change to define the amplitude directly in a harmonic analysis.

Cheers,

Alex
