Dear Stephan,

regarding point 1, please recompile the current svn version of getfem++. Regarding point 2, which language are you interested in? Python/Matlab or C++? For Matlab you can look at interface/tests/matlab/demo_nonlinear_elasticity.m.

Dear Yves and Sébastien,

I may have a related issue. I am trying to implement an axisymmetric system, first for linear elasticity and later on for more complicated models.
I would have two questions:

1) When I try to compile the version 4.3 from the link Yves sent I get the following error:

libtool: compile:  g++ -DHAVE_CONFIG_H -I. -I../.. -I../../src -I../../src -DGMM_USES_BLAS -I/home/btpj/bt301429/muparser/include -I/usr/include/mumps -DGMM_USES_LAPACK -fpermissive -O3 -Wall -W -fmessage-length=0 -ftemplate-depth-100 -pedantic -Wshadow -Wno-unknown-pragmas -Wno-variadic-macros -Wno-unused-but-set-variable -Wpointer-arith -Wcast-qual -Wwrite-strings -Wconversion -Wredundant-decls -Wno-long-long -MT gf_asm.lo -MD -MP -MF .deps/gf_asm.Tpo -c gf_asm.cc  -fPIC -DPIC -o .libs/gf_asm.o
gf_asm.cc: In function 'void asm_stabilization_patch_matrix(const MAT&, const getfem::mesh&, const getfem::mesh_fem&, const getfem::mesh_im&, bgeot::scalar_type, bgeot::scalar_type)':
gf_asm.cc:218:42: error: 'h' was not declared in this scope
   nparts = int(size_of_crack/(ratio_size*h));

2) Is there an example of how to implement simple linear elasticity with the new high-level language? The examples on the website are helpful, but they only show a few lines of code. It would be very helpful (to me at least) to have a full running program. Does that exist?
One could then use this as a basis for extensions.

Best regards,

  Stephan

Subject: [Getfem-users] Getfem version and non linear elasticity
        models

Hello !
I've recently begun to use Getfem with its Python interface.
My first question is that the latest version available on the GNA
download page is 4.2 but the documentation is for version 4.3. Is a
documentation for version 4.2 available somewhere (I've not found it on
the website)?
Maybe this is related with my problem with non linear elasticity models:
I'm trying to use 'neo Hookean' model for some small calculations, but I
get the error
"RuntimeError: (Getfem::InterfaceError) -- neo Hookean is not the name
of a known hyperelastic law. \Valid names are: SaintVenant Kirchhoff,
Mooney Rivlin or Ciarlet Geymonat"
when trying to use the brick "md.add_nonlinear_elasticity_brick(mim,
'u', 'neo Hookean', 'cHookean', region)"

I also didn't manage to use either compressible or incompressible
keywords for Mooney-Rivlin model.
Do I miss something? Will these syntax and models only be available for
version 4.3?

Thanks in advance
S. Lherminier
