This dialog window assists extraction of the thermal data specific for the crystal region. The number of the crystal region is identified by generating of the structured mesh if the phase transition is defined by a pair of the crystal and melt regions in contact. The phase tracking procedure may be then activated and the shape of the crystal-melt phase interface can be computed by means of the phase tracking.

The shape of the phase boundary crystal-melt, the values of the temperature in Kelvin and of the axial temperature gradient in K/m on it can be retrieved for the phase boundary. Additionally three different temperature profiles and related data can be evaluated inside of the crystal. All data is written then into a file. The written data is ordered into columns. In the beginning of the file a header is placed where the meaning of data is described.

The stored data amount is controlled by settings of the dialog window. All available data is listed below.

**radial coordinate [m]**Radial position of the point at the phase boundary crystal-melt. The point is located at the shared region boundary between the crystal and melt regions.

**phase boundary axial coordinate [m]**Axial position of the same point. The position can be modified by the axial shift during the phase tracking.

**temperature at phase boundary [K]**Absolute temperature at the region boundary coinciding with the phase boundary. In the converged state of the thermal computation with the phase tracking the temperature at the whole region boundary between the crystal and melt regions should be equal to the temperature value at the triple point (the most radially extent point of the shared boundary). The temperature of the triple point is regulated usually to be equal to the prescribed melting point temperature. A control temperature point is placed onto the triple point location. The triple point position is anchored, it doesn't change during the phase tracking procedure.

**axial gradient at phase boundary [K/m]**Value of the axial component of the temperature gradient computed inside of the crystal region directly at the region boundary coinciding with the phase boundary crystal-melt.

**axial coordinate [m] of the first isotherm in K**Axial coordinate of the first isotherm inside of the crystal region defined by the temperature value.**temperature [K] of the first isotherm in K**Real temperature in the considered points of the first isotherm. The temperature values are stored for the consistency check, they all should be equal to the value defined for the first isotherm.**axial distance to the phase boundary [m]**Height difference between the first isotherm and the phase boundary crystal-melt.**axial coordinate [m] of the second isotherm in K**Axial coordinate of the second isotherm inside of the crystal region defined by the temperature value.**temperature [K] of the second isotherm in K**Real temperature in the considered points of the second isotherm. The temperature values are stored for the consistency check, they all should be equal to the value defined for the second isotherm.

**axial distance [m] between the first and the second isotherm**The distance between the defined isotherm lines is a function of the axial temperature gradient in the crystal and the temperature values of both isotherms.**axial coordinate [m] of the third line**The third analyzed line in the crystal can be prescribed either by a given axial distance in meter from the phase boundary or as a horizontal line at some absolute axial coordinate (height). The axial coordinate of the third line will depend on the shape of the phase boundary in the first case and will coincide with the prescribed axial coordinate value otherwise.

**temperature [K] at the third line**The absolute temperature in the considered points of the third line.

**axial gradient [K/m] at the third line****axial distance to the phase boundary [m]**Distance between the third line and the phase boundary. If some definite axial distance between the phase boundary and the third line is prescribed, then it coincides with the value of the distance. Otherwise it depends on the shape of the phase boundary crystal-melt.

Following items of the dialog window are used:

Axial distance or coordinate for definition of the third profile in the crystal. It can be interpreted either as a distance between the third profile and the phase boundary or as an absolute axial coordinate of the profile in dependence on the following dialog settings.

** parallel to Phase Boundary**
Checkbox sets the kind of the third analyzed profile in the
crystal region as parallel to the computed shape of the phase
boundary.

** at fixed height**

An alternative possibility to set the third analyzed profile as a horizontal one with the defined axial position.
