Stress Recovery

Good morning/afternoon, teachers. During the stress recovery process, I observed that the strain exhibits a significant gradient along the thickness direction of the airfoil, which normally should not occur.

This is an enlarged view of the area with a significant strain gradient.

@su.tian.22 can you take a look at this?

The plot you attached here is for stress, not strain. You can go to the left panel of gmsh to switch between different stress/strain components.

I am very sorry, I made a mistake. This should be the graph corresponding to strain.

This is the strain distribution diagram for the various local regions of the airfoil.

Additionally, I would also like to ask what directions these stresses represent.

What are the versions of PreVABS and VABS you are using?

You can check the manual for more details.
