Dear Jean,
I followed your suggestions and used the first method (triangulation
iterator outside of loop and two dofhandler iterators inside of loop).
After making sure of this, I managed to fix several other bugs and finally
the code works well. And the results are nearly the same as the
Dear Toddy,
This is a link to the documentation, where this function (a class constructor)
is explained in more detail

Professor Wolfgang,
Thanks for your advice and I will try my best to do what you told me. I
asked the problem about the transform between dofhandler iterator and
triangulation iterator because I have never used this function. Except this
function, I 'm familiar with the other functions used in

Hi, Jean
I used the method that you taught me. but unfortunately the results seems
bad. And I'm not sure where the problem is including the transform between
dofhandler iterator and triangulation iterator. So please take a look at my
codes(two pieces of codes shown in the following figures)
Hello, Jean
I'll look at the material and have a try. Thanks for your help
Best,
Toddy

Hi Toddy,
It’s possible to convert a triangulation iterator to a DoF iterator using the
technique described here:

Dear Deal.II community,
I'm programming on modifying step 35 using Parallel computing with multiple
processors using distributed memory. In step35, the tutorial program used
"synchronous" iterator which consists of two iterators, one for velocity
and the other for pressure.
Now I'm struggling
