For future reference, if you are in doubt on how to use a single
class/function, you can skim through the directory tests, i.e.,
tests/manifold/composition_manifold_*
would have shown to you an example which is identical to what you are trying to
achieve, and in general it contains very simple
I was making a mistake. Reading the code of CompositionManifold clarified
it. This is correct
static const PolarManifold<2,3> sphere;
static const FunctionManifold<3,3,3> rotate("x;-z;y","x;z;-y");
static const CompositionManifold<2,3,3,3,2,3> rotated_sphere(sphere,
rotate);
Hello
I think I understand this better after reading the code. Here is my attempt
static const PolarManifold<2,3> sphere;
static const FunctionManifold<3,3,3> rotate("x,-z,y","x,z,-y");
static CompositionManifold<2,3,2,3,3,3> surface(sphere, rotate);

Having curved boundaries alone is not sufficient sometimes. One would like
to use curved elements in the interior also. It would be very useful if one
could read high order meshes, e.g., from gmsh. The extra nodes can be used
to create an euler vector that can be used in a MappingFEField.

Sounds like we ran into the same problem

this issue in serial.

Hello everyone,
So firstly, I'm using version 8.3.0. If this is a real bug but has been
addressed in a newer version please let me know, but I have not found any
info about it in the change logs up to version 8.4.2 or the user group.
I'm using a block matrix to solve a steady, variable density
That seems to have been the issue. I had to install libblas-dev,
liblapack-dev, and libatlas-base-dev but the program installs normally now.
Thanks,
Andrew

Chenchen,
We only support to read in meshes that are not refined. Translated to your
situation this means that you are only able to use Q1 meshes as initial
grid.
Of course, you can then use triangulation.set_manifold to define the
correct behavior when you refine your mesh within dealii along
Chenchen,

liblapack.so is typically a symlink to a versioned shared library
liblapack.so.X. It might simply be a stale symlink (pointing to a
nonexistent file).

Hi all,
I have to use quadratic shape function (Q2 elements) to do my project (2D).
Previously the code works well with Q1 linear elements, when I want to
input the gird with Q2 elements generated by Gmsh, it gives the following
error:
An error occurred in line <1418> of file <../source/gr
This is probably a really simple question to answer, but I haven't found
the fix yet.
I recently upgraded my Ubuntu distribution to 16.04 and I'm trying to
recompile deal.II (version 8.3) for the new OS. Note that I'm using version
3.4 of CMake which comes packaged with Ubuntu 16.04. Everything
Dear all
I am trying to compose two manifolds. I want to apply a 90 deg rotation about
x-axis to PolarManifold to obtain description of surface of sphere and thereby
avoid the poles.
So I try something like this
static PolarManifold<2,3> sphere;
static FunctionManifold<3,3,3> rota
