mpirun -np 4 feelpp_toolbox_solid --case "github:{path:toolboxes/solid/cases/NAFEMS-LE1}"
mpirun
Case option
--case "github:{path:toolboxes/solid/cases/NAFEMS-LE1}"
3. Data files
The case data files are available in Github here

The value of σyy at the point D is 94.09MPa for 32000 dofs, which is 1.49 higher than the target.
One possibility to get a more accurate output is to use a mixed formulation, where the stress tensor would also be an unknown. |
We now display the displacement field and the Vonmises stress field.
