Dear Seyed Ali,
but this does not make sense since the finite
element approximation on one element is far from being meaningful.
Anything you obtain has a huge discretization error.
In addition, this result will not be independent of phase-field.
I would rather do it as we did (and usually done in numerics),
to compare the method to other published results or to
compute a solutions on a sequence of meshes.
For instance in the crack code, we compared our results
to Miehe et al. and Borden et al.
Best regards,
Thomas

Dear Thomas,
I would like to check the elastic energy you compute and compare it to
my results. For a single element the computation in an elastic regime
should be independent from the phase-field approach in primary steps.
BR,
Seyed Ali
