# Method of solution | ||
A fully implicit numerical algorithm is used that allows both Newton-like iterations to steady state | ||
and time-dependent solutions with large time-steps. A preconditioning matrix is obtained by approximate | ||
(ILUT) inversion of a numerical finite-difference Jacobian, which is then used in a Newton-Krylov | ||
solution algorithm. A finite-volume differencing algorithm is used. Over 95% of the coding is in | ||
Fortran with the remainder being C. | ||

||
Although UEDGE is written in Fortran, for efficient execution and analysis of results, it utilizes | ||
either Python or BASIS scripting shells. Python is easily available for many platforms | ||
(http://www.Python.org/). The features and availability of BASIS are described in "Basis Manual Set" | ||
by P.F. Dubois, Z.C. Motteler, et al., Lawrence Livermore National Laboratory report UCRL-MA-118541, | ||
June, 2002 and http://basis.llnl.gov/), however, BASIS is deprecated. Contact one of the UEDGE developers | ||
if you insist on running it within that environment. | ||
The Python version of UEDGE uses the same source files but utilizes Forthon to produce a Python-compatible | ||
source. Forthon has been developed by D.P. Grote (see http://hifweb.lbl.gov/Forthon/ and Grote et al. | ||
in the references below), and it is freely available. The graphics can be performed by any package importable | ||
to Python, such as PYGIST. The parallel version of UEDGE available through Python also uses the PETSc linear | ||
algebra solver whose development has been led by ANL (https://www.mcs.anl.gov/petsc/). | ||
|
||
UEDGE can also be coupled to other codes. An excellent example is couplling to the DUSTT code from | ||
UCSD (contact [email protected]) that follows the trajectories and ablation of dust particles in | ||
the background UEDGE plasma and provides impurity sources to UEDGE. For an example, see R. Smirnov | ||
et al., Phys. Plasmas 22 (2015) 012506. | ||
