Dear All
I have a success of *block_write* and *block_read* in storing
*Vector::BlockVector* for post processing
*https://www.dealii.org/8.4.0/doxygen/deal.II/classVector.html#aef98e4994a6c0b20bb33b0290f8d607c*
Now, I would do similar in *dealii::LinearAlgebraTrilinos::MPI::BlockVector*
but
Thanks for the clarification, Jean-Paul. I'm glad to hear that my syntax is
correct.
I am indeed using an extractor, e.g. here's a line from my code:
const Tensor<2, dim> gradv = fe_values[velocity].gradient(j, quad);
I'm having some trouble finding an example of the S[i][j] syntax in either
Hi Artur,
I am trying to install these by myself, it would be great that you can
share your installation steps, did you configure deal.ii with petsc? If so
did you use the available version or also install it by yourself?
Thank you,
Zhenlin

I'm sorry to say that you shouldn't be too quick in this instance to thank
me...

Hi,
I am trying to run deal.ii on Stampede after loading following modules, I
can compile the code:
1) xalt/0.6 3) git/2.7.0 5) intel/15.0.2 7) mvapich2/2.1 9)
dealii/8.4.1 11) slepc/3.5
2) TACC 4) cmake/3.7.1 6) cxx11/4.9.18) trilinos/12.6.4 10)
petsc/3.5
Hi Bruno,
To load trilinos/12.8.1 I have to load gcc which is against intel/15.0.2
that is necessary to load dealii.
I load the python module, but the error is still there, probably I will try
to install trilinos and deal.ii bymyself.
Thanks,
Zhenlin

I am debugging a code where part of my weak form requires indexing into the
Tensor<2,dim> that results from getting the gradient of a Tensor<1,dim> (in
this case, a velocity vector).
I found the convention for the index notation
here:
Dear all,
I recently found the thread: Something wrong with ChartManifold when
chartdim=1:
https://groups.google.com/forum/#!topic/dealii/Sfo9xKoeRpw
a more straight answer to this thread.
I took the liberty to copy David's code and modify it, so that the upper
face of a square follows:
Dear Alex,
What you've stated is correct. The tensor component $S_{ij}$ is exactly
component S[i][j] of a Tensor<2,dim> S if "S" represents $S_{ij} = \partial
v_{i} \partial x_{j}$.
As for an example, both steps 18
Zhenlin,

Zhenlin,
I remember having trouble getting deal2 to compile against the available
versions of trilinos. In the end, I just ended up installing both myself.
If you want, I can post my installation steps.
Rgds,
Artur
