Yes, FEFLOW uses multiple CPUs/cores on one single machine ('shared-memory parallelization'). This is automatically done for lots of tasks such as matrix assembly, but the default equation system solver is NOT working in parallel. So to use paralellization for the matrix solution process as well, try to use either PARDISO or SAMG as the solver.

Sets leakage boundary conditions (flow exchange between a river and groundwater) for large scale groundwater models. The plug-in enables single node 3rd order boundary conditions in 2D and 3D models. Leakage parameters (leakage coefficient for inflow and outflow).

Exports hydraulic heads and optionally concentrations to TECPLOT *.plt format (TECPLOT release 10), so that TECPLOT can be used to postprocess and visualize the results. 2-D and 3-D models with triangular and quadrangular discretization are supported.

Root water uptake from the complete Feddes model. The parameters required for Feddes model implementation such as the number of sink elements considered, the value of pressure head of each sink element and the stress function as well as the width and the area of the root zone, were computed during the simulation period and summarized in ASCII file (*.out1). 8)

This plug-in calculates density effects due to pressure and temperature changes in Discrete Feature Elements (DFE) and finite elements. Density is calculated using the same equations as the BetaGamma IFM plug-in, incorporating pressure and temperature effects (T = 0 ... 350° C and p = 0 … 10Mpa).

The plug-in regards the fluid density related to temperature, pressure and concentration and sets the fluid density after each time step for all matrix and discrete feature elements. The following reference values for concentration C_0 = 0 g/l, C_S = 350000 mg/l, pressure p_0 = 100 kPa, p = 10MPa and temperature T_0 = 0C, T = 350C were set. The density equation of state was adjusted by means of sodium chloride concentration.

The map view in FePEST is currently similar to the Slice View in FEFLOW itself. In case of a tetrahedral mesh, there are no slices and thus nothing is shown. You'd need to use the 3D view in FEFLOW to look at your data.
