Discretization schemes, micromixer tutorial

Dear Comsol users,

I kindly ask you to help me with the following task. I have to specify the discretization schemes employed in my model. Since I used an existing tutorial model 'micromixer.mphbin' and did not change any of the tutorial's solver procedures could you please help me specify/identify the discretization schemes employed?

I tried to get this information from the tutorial's pdf (under 'Study 1' section) though unsuccessfully.
Thank you very much for your help,
best regrads!
