Dear Yaakov,

which article do you mean? Please give the exact reference including author names.


I do not know a priori whether they have different material parameters, another
stress-strain splitting, etc.

The reason for different results can be anything. One needs to do a careful 1-by-1
comparison.

Best regards,

Thomas W.

Dear Prof. Wick,

I have used isotrope formulation for miehe shear loading (without local refinement). I ca not see two crack branching which is described in the article (A review on phase-field models of brittle fractureand a new fast hybrid formulation)

I attach the test results.

Thanks for your answer!

Kind regards,
Yaakov

    Hello,

    there are two flags in the parameter file that you need to change:

    set Decompose stress in rhs               = 0.0
    set Decompose stress in matrix           = 0.0

    Dear Prof. Heister, I would like to just test  isotrope
    formulation of phase -field model (no compression/tension
    modification), how could I modify the codes (in a simple way)? I
    am sorry that I am just a beginner of DealII. Best On Tuesday,
