How does the live plot point work?

[csuvi98]

Hello!

I just started using DICe for my thesis and was wondering how exactly live plot points work. Do they track a subset-sized area (with the live plot being the center) or do they track displacement differently?

For my use case, a few subsets (around 5-10) would be enough, I don't need to do full-field displacement, so that's why I thought only placing these points, but I couldn't find out how they work exactly.

Hi csuvi98,

The live plot points provide a way to view the results at specific points in the domain for which the results data gets interpolated from the nearest subsets. All of the tracking/deformation gets computed at the locations for which you have subsets defined. To create the live plots, this information gets interpolated to the points of the live plots. If you only need a few subsets, you can define the specific locations using a subset file (see here http://dicengine.github.io/dice/#UserManual). As opposed to the live plots which interpolate from the nearest subsets to the live plot points, using a subset file will create subsets at those points so no interpolation is needed and your results files will also be collocated to those locations.
