[Paraview] Saving a dataset as a parallel output

[Xiaogai Li]

Hi Everyone,

I have a question about paraview python calculator "strain".

My questions are:

1. If want to calculate strain form a displacement field (3 component
vecotor),
is it correct to use directly

strain(deformationfield_vector)

2. If the above is correct, then what kind of strain is it?
Is it infinitesimal strain, Green-Lagrangian, or Euler-Almansi strain?

I tried to search from the internet, but couldn't find any related answers.

Thanks for attention.
BR,
Zoe
