sfepy.scripts.simple module¶
Solve partial differential equations given in a SfePy problem definition file.
Example problem definition files can be found in sfepy/examples/
directory
of the SfePy top-level directory.
In the examples below it is supposed that sfepy is installed. When using the
in-place build, replace sfepy-run
by python3 sfepy/scripts/simple.py
.
The supported application kinds (–app option) are:
bvp - boundary value problem. Example:
sfepy-run sfepy/examples/diffusion/poisson.py
homogen - calculation of local microscopic problems (correctors) and homogenized coefficients. Example:
sfepy-run sfepy/examples/homogenization/perfusion_micro.py
bvp-mM - micro-macro boundary value problem. Solve a coupled two-scale problem in parallel using MPI. One computational node is solving a macroscopic equation while the others are solving local microscopic problems and homogenized coefficients. The –app option is required in this case. Example:
mpiexec -n 4 sfepy-run --app=bvp-mM --debug-mpi sfepy/examples/homogenization/nonlinear_hyperelastic_mM.py
evp - eigenvalue problem. Example:
sfepy-run sfepy/examples/quantum/well.py
phonon - phononic band gaps. Example:
sfepy-run sfepy/examples/phononic/band_gaps.py --phonon-plot
Both normal and parametric study runs are supported. A parametric study allows
repeated runs for varying some of the simulation parameters - see
sfepy/examples/diffusion/poisson_parametric_study.py
