So how can I possibly implement heat flux on cell faces in this example
case step-26 ? If I can, then I guess my problem is solved to learn
implementing Neuman BC for Heat equation in deal.ii. Thank you very much in

Hi Andrew! I am also working on the same problem and would be interested to
have a look into Thesis but the link says it has been removed.

Dear Prof Wolfgang,
Hi! I am successful in running the code and
it is without a doubt a nice addition to deal.ii code gallery. It
reproduces the expected result for 3d Beam case now.
Since I did not find any thermomechanical coupled example so far in deal.ii

It seems that "tmp" vector stays unchanged i.e. function is seemingly not
assigning any face rhs values to "tmp" vector.

Thank you for the suggestion and I also think it can be one
of the way to successfully run both solutions by sharing information on
correct corresponding q_points.
I tried the same approach (as I am also using partitioned approach for
thermomechanical coupling) but so

Great idea Prof. Bangerth. Thanks!

Dear Prof. Wolfgang,
Thank you for sharing the tutorial step.
I am using the plasticity (material non linearity) part of it with the
surface force (Neuman BC) as a mechanical load. When I remove the load the
plasticized domain comes back to its original
Looking forward to your guiding response. Thank you once again for your

Dear fellow community members,
Hi! I want to
simulate some simulation cases based upon the elastoplastic material model.
They involve the loading and then unloading of the material too. I tried
with the step-42 but apparently it is
es attached. Looking forward
for your guiding response!
Thank you very much for ongoing cooperation.
