Dear Stephan,

This should be fixed now (you can download on the same link again).

For the moment, you can find some examples of use of the new assembly in 
tests/test_assembly.cc but without the model objects and in 
interface/tests/matlab/demo_nonlinear_elasticity.m using the model object but 
this is a nonlinear case).
The easiest way to use the new generic assembly is to use the corresponding 
bricks described here

Yves.

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
