ThermoElectric2D
(name)¶Thermoelectric calculations solver without the optical part.
This solver performs underthreshold thermoelectrical computations. It computes electric current flow and temperature distribution in a self consistent loop until desired convergence is reached.
The computations can be executed using compute method, after which
the results may be save to the HDF5 file with save or presented visually
using plot_...
methods. If save
parameter of the compute()
method
is True the fields are saved automatically after the computations.
The file name is based on the name of the executed script with suffix denoting
either the launch time or the identifier of a batch job if a batch system
(like SLURM, OpenPBS, or SGE) is used.
