hi,
i have a problem with the field output. i´d like to visualize the components of the deformation gradients (DG) but the following error appears when i toggle on the option for DG in the "strain"-list and start a calculation:
"Output request dg is only available for *hyperelastic/foam and *user material."
i don´t understand this error, because i have chosen the neo-hookean model, which is indeed hyperelastic.
can anybody help me?
