Element data format can only hold displacement and not rotation
Dear GMSH development team,
GMSH can be very useful in post-processing DEM (Discrete Elements Method) data; where there are almost no alternative software and GMSH has the potential to fill this gap and become a popular software among researchers in this field by what seems like a minor improvement.
While GMSH can save displacement data of elements and visualize them, currently there is no option to save element rotations in element data field.
Best regards, Mehrpay
