The name is somewhat misleading. ‘ssi: shear strain increment’ is just ‘total shear strain’ . What it means is the increment in shear strain since the last time displacements were set to 0…

I have sort of similar doubt, i just wanted to plot contours of strain using fish apart from strain increment and strain rate. please provide any ref
how to calculate and plot the contour of strain in a model ??
Contour of strain can be plot via PLOT->Model->Contour_Zone->Strain. Strain calculations examples can be found in the Fish Reference manual: Section 2.5.3.3 Strain Calculations.
I just want to calculate strain instead of strain rate and strain increment
