SET_DIAGRAM_AXIS

Specify the axis variables of a plot. At least two axis variables (x and y) must be specified.

Also see Auxiliary Variables, Integral Variables, and State Variables in Console Mode DICTRA for lists of variables including its abbreviated name (i.e. the mnemonic) as well of the names of these variables.

Syntax

set_diagram_axis

Prompts

Axis (X,Y or Z)

Specifies the axis to set a variable.

 

Variable

Specifies the variable to plot along this axis. A variable is specified by its mnemonic (i.e. its abbreviated name) or by name. The variable types are None, Integral Variables, Functions, Auxiliary Variables or State Variables.

  • NONE: Use this variable to clear an axis setting.
  • INTEGRAL VARIABLES: A quantity obtained by integration in space over the whole system or over a specific region. In a planar geometry values are given per unit area, in a cylindrical geometry they are given per unit length, and in a spherical geometry they are absolute values. See Integral Variables for examples.
  • FUNCTIONS: These are identified by a name which is entered with the ENTER_FUNCTION command. Use the list_symbols command to get a list of valid function names.
  • AUXILIARY VARIABLES: As a complement to state variables and integral variables the auxiliary variables are defined. The variables can be called by their mnemonic names, which are shown in the rightmost column. These are useful in user-defined functions. See Auxiliary Variables for examples.
  • STATE VARIABLES: State variables in the DICTRA POST module are similar to those defined in POLY-3. Examples of state variables are temperature, mole fraction, enthalpy, etc. In POLY-3 a general notation method based on character mnemonics is designed for a predefined set of state variables. See State Variables in Console Mode DICTRA for examples.

Depending on the axis variable some sub-prompts may be available.

 

For component

When an activity, flux, mole-, weight- or U-fraction or percent is plotted the name of the component must be supplied.

 

In region

When the lamellar spacing, e.g. for pearlite, is plotted the name of the region must be supplied.

 

For phase

When the lamellar thickness, e.g. for ferrite in pearlite, is plotted the name of the phase must be supplied.

 

Interface

When the velocity or the position of an interface is plotted the name of the interface must be given. An interface is identified by the name of the region on its upper side.

 

Type

When choosing distance as variable one has additionally to specify what type of distance. A distance may be GLOBAL, i.e. counted from the leftmost interface, or LOCAL, i.e. counted from the interface to the left of the region whose name you are prompted for.

 

Region name

Name of the region wherein the local distance is measured.
