Hello,

Sry if this seems trivial. I am trying to learn Paraview post processing from Simvascular vtp/vtu files. I was trying to see if it is possible to export engineering stress and strain/stretch outputs from paraview.

My outputs that I am getting with “plot over line” filter are “GlobalNodeID”, “avg\_pressure”, “avg\_speed”,“displacement"0”,“displacement:1”,“displacement:2” ,“pressure”, “timeDeriv:0”, “timeDeriv:1”,“timeDeriv:2”, “timeDeriv:3”, “vWSS:0”, “vWSS:1”, “vWSS:2”, “velocity:0”,“velocity:1”, “velocity:2”, “vinplane\_traction:0”,“vinplane\_traction:1”, “vinplane\_traction:2”, “wallproperty:0”, “wallproperty:1”, “GlobalElementID”,“vtkvalidPointMask”, “arc\_length”,“points:0”,“points:1”, and “points:2”.

velocity and pressure and alike are straight forward, although I am unsure of what vinplain\_traction, wallproperty, and Global Node/Elements are. I assume vinplane\_traction is a stress tensor for velocity-based simulations.

Would anyone be able to explain how I might get stress and strain/stretch from Paraview, if say for instance I am working with a cylinder Coupled moment method fluid structure interface simulation? Or what filter is best suited for finding strain?
