Dear Jean-Paul,
Thanks very much for your explanations.
I managed to achieve my objective. You were right, one of the crucial
points I had to take into account was the compatibility of data structures.
Defining a new operator was another to the point advice, as some of the
errors were laid on
deal.ii users,
I'm learning deal.ii with the goal of using it to non-linear solid
mechanics problems. In many of these problems (such as Step-44), a time
step is used to move a calculation from the initial condition to the final
loaded state.
Step-44 uses a uniform time-step, but there are
Hi, Daniel,
I see. Thank you very much. So, I think our method may be available as long
as it can separate the face.

Hi, Bruno,
Thanks a lot. We will have a try based on the example you gave us.

Xiang,
deal.II doesn't have functionality to create separate cells sharing a face
but only to join them. Hence, whatever input you provide to
Triangulation::create_triangulation() must have these faces already. GridIn
should work for that if the faces are disjoint in the input file.

Daniel

Xiang,
Here is an example on how to do it:

As you can see, you need to know which dof you need to constrain

Hi,
Although you have set -DDEALII_WITH_MPI=ON it seems from the following
lines in your output :
-- Found LAPACK
-- Use other than Intel MKL implementation of BLAS/LAPACK (consult
CMakeFiles/CMakeError.log for further information).
-- DEAL_II_WITH_LAPACK successfully set up with external

Hi, Daniel,
Thank you very much. So, if I want to disjoint the faces, how should I do
using dealII or I need to disjoint them manually? If I manually disjoint
them, should I duplicate the joint nodes and assign them with the new
number, then assemble the adjacent element with the duplicated

Hi, Bruno,
Thank you very much. Does the AffineConstraint force the value at the
specified DOF? I need to how the node numbers map to the DOF, right?
