Translations:Extend FEM Module/12/en

In FreeCAD a solver can be split into two parts. One is the document object used by the user to interact with the solver. Though it solver parameter can be set and it is also used to control the solving process. The other one are the so called tasks of a solver. The solving process is split into those tasks, namely: check, prepare, solve and results. Those do the actual work of exporting the analysis into a format understood by the solver executable, starting the executable and loading the results back into FreeCAD.
