Compression plots

Please login with a confirmed email address before reporting spam

Hello,

I am simulating a model to see the interaction of electric field of a tip (like AFM tips) on a electrostriction substrate surface. In the model, I am trying to insert a defect in the material. I need a plot of the strain or compression the surface suffers when the tip is polarized, which characterizes a electrostriction effect. But in the plot I could not find a way to plot the strain in 2D, just the stress. How can I plot the plot equivalent a compression effect in th results?

I have another question regarding the electrostriction effect: how can I add this effect? I used the coupling for electrostriction and added the Q electrostriction tensor, is this enough? It seems to me that I am missing something.

I am sending a printscreen of the physics I am aplying to my model, as the geometry of my problem too.

Hope someone can help, thank you. Hugs, TMV

I am not certain that I fully understand your question. There are many types of strain results available in the result menus, including strain components in local directions, and the principal strains. See the attached screenshot.
