Hi,

Referring to [1], we can use defToVtkFromPositions() to write a vtk file to visualise the deviatoric strain filed in paraview. For example: defToVtkFromPositions(position1.txt,position2.txt,"output_deviatoricStrain.vtk"). In this vtk file, it can show: solid color, strain_deviator and strain_matrix. It seems that no volumetric strain field from this vtk file.

I would like to ask how to write a vtk file to visualise the volumetric strain field.

Thanks.
Leonard
