USE_INTERPOLATION_FOR_D

In Graphical Mode, Complex is the default and cannot be changed.

An interpolation scheme can be used to calculate the chemical diffusivities of complex phases. If this is enabled, the performance gain from this ranges in orders of magnitude. This is ON by default for complex phases and can be set to OFF with this command.

Prompts	The following phases will be affected if complex is selected: When there are phases in the system that will be affected, these are listed. The phases are based on the thermodynamic model. Interpolate diffusivities in /None/Complex/All phases /Complex/ The default is `Complex`. A complex phase means that an equilibrium calculation is needed in order to determine the site-fractions in a phase with converting from u-fraction (or any other type of composition variable).
	Enter number of steps between Xmin and Xmax /10000/: Enter what is essentially the number of steps in each dimension in composition-P-T space for each equilibrium condition (Nk, P, T). In the limit where an infinite number of steps are used, exactly the same solution is obtained as without the interpolation scheme. However, excellent results can be obtained with a reasonable discretization.
	Linear or Logarithmic discretisation /Log/: The discretization can be either linear or logarithmic. For the linear discretization the scheme will not be used at node points where the content of one or more solutes fall below a certain critical value. For such cases, where composition span many orders of magnitude, the logarithmic discretisation can be tried.
	The system confirms the discretization setting and displays the amount of free memory available for the calculation. You are prompted to enter how much of this memory to use for the simulation. Discretisation set as Logarithmic (or Linear) Free physical memory (mb): 8535 Fraction of free physical memory to be used /.1/: The fraction of free physical memory to be allocated for the interpolation scheme.
