Solution dialog box (Multiphysics), Articulation Parameters page

This page appears when Analysis Type is Thermal or Coupled.

Option	Description
Time Step Option	Specifies how the thermal solver calculates the time steps for the articulation modeling. View factors, radiative conductances, and thermal couplings are recomputed at the specified time interval.At Constant Time IntervalsCalculates the time steps using a constant size that you define. You set the start and end times in the Start Time and End Time boxes, and the time interval between two sets of articulation calculation in the Calculation Interval box.Total NumberCalculates the time steps by dividing the articulation simulation time interval by the number of articulation time steps. You set the start and end times in the Start Time and End Time boxes, and the number of articulation time steps in the Number of Time Steps box.At Specified TimesCalculates the time steps at times that you specify. Select the time units from the Articulation Times list, and enter the discrete articulation calculation times in the Articulation Times text box. Use commas to separate the calculation times or enter the times on different lines. You can use the Cut , Copy , and Paste commands. Interval versus Time TableCalculates the time steps using a defined time step size that varies with time. Use Specify Field to select or create the time step variation table. You can uniformly increase or decrease the dependent variable in the field by the factor you specify in the Scale Factor box.For example, if you specify the following time step variation.TimeInterval0.01.06.02.016.03.4The solver performs the articulation calculation at the following times:0.01.02.03.04.05.06.08.010.012.014.016.0The last row of the table indicates the last articulation calculation time; the interval value is a placeholder number.Specify Field lets you select or create the time step variation table. See Specify Field options.	Time	Interval	0.0	1.0	6.0	2.0	16.0	3.4	0.0	1.0	2.0	3.0	4.0	5.0	6.0	8.0	10.0	12.0	14.0	16.0
Time	Interval
0.0	1.0
6.0	2.0
16.0	3.4
0.0	1.0	2.0	3.0	4.0	5.0	6.0	8.0	10.0	12.0	14.0	16.0

Specify Field options

These options are available when the magnitude is defined as Field.
Select Existing Field from List	Lets you select an existing field to specify an articulation time step that varies with time.
Formula Constructor	Lets you use a formula to construct a field. For more information, see Define a boundary condition using a formula field.
Table Constructor	Lets you use a table to construct a field.For more information, see Define a boundary condition using a table field and Define a material property using a table field.
Link Constructor	Lets you reference an existing field. You can override the field's spatial map to use the field in another location.For more information, see Linked Field dialog box.
Plot(XY)	Plots the field as an XY graph.For more information, see: Plot functions, Graph overview, and Edit display properties of graph objects.
Overlay(XY)	Available when a plot is already displayed. Overlays a plot on an existing plot. You can overlay up to 50 plots. For more information, see Overlay plots.
