Dear Roy, dear Paul, dear all,
I am testing AMR in libmesh using simple linear elements.
My test case is a propagating front described by a reaction-diffusion equation
with a cubic bistable reaction term.
I followed the adaptivity examples to create this test case.
The run times for 100
Dear all,
I’m trying to implement a DG formulation for solid mechanics using linear
elements.
I’m currently using the following strategy:
I define my variables as MONOMIALS but in the assembly I pretend my FEType is
LAGRANGE.
This gives me the correct values of the shape functions on the edges.
I have the --disable-unique-ptr option in my configuration script since it is
required by another library I’m using on top of libMesh.
Thanks,
Simone

Dear all,
I’m upgrading to PETSc 3.7.4 and I am now compiling the git version of libMesh.
On my workstation (using gcc 5.4 and openmpi 2.0.0) I get a compilation error

Hey John,
I’m using PETSc 3.7.2. I’ll install a another version to check if that’s the
problem.
Thanks,

Dear all,
I have been trying to run some of the time dependent examples.
Every time I use the -ksp_monitor command line option (with PETSc) to see the
output of the linear system,
after 4 iterations the simulation crashes saying that there are too many
kip_monitors.
The same thing happen when

Dear all,
I’m playing around with the elasticity tests in the system of equations
examples (more specifically Ex4 and Ex5).
In particular I’m trying to set the poisson ratio to nu = 0.49995.
With this choice the solution I get using second order lagrangian elements does
not make any sense.

so it is already implemented. It sounds awesome.

Dear all,
I’d like to extend my libmesh-based reaction-diffusion solver to a surface
solver,
taking the trace of the 3D shape functions on the surface mesh.
Before I start implementing a new element,
do you have any suggestion on how to approach it?
Thanks,
Simone
Hello,
I’m experiencing a runtime error when export the equation systems if I use more
than one EquationSystems with different variables in each system.
In particular, I created 2 EquationSystems: systems1 with one P1 variable and
systems2 with two P1 variables. After initializing, I write the
