What's the possible reason for incorrect prescribed displacement in static analysis?

Discussion created by Louise Yi on May 18, 2020

I want to run a static analysis for a model. There is a 0.1mm prescribed displacement for an edge. It does not pop up any error but the result is a much larger displacement. 


The picture below is the model and the result. The grey line highlighted with red arrow is a marker where the fin should reach. Apparently the resulting displacement is much further.

Any idea about it? Thanks

(Attached is just an example model, the material does not matter. )



It solved. The reason is the incorrect deformation scale setting. After setting it as true scale/1, it reveals the actual deformation. Thanks for Julien Boissat answer.
