Settings

Under “Settings,” various global parameters and visualisation options can be modified. For each of the categories, various parameters and display settings can be modified. In general, various elements of the three diagrams turned on or off, and the colors of the elements can be customised. The modifiable parameters for each category are summarised below.

RV2

tol

• angles (float (5.0)) - Angle deviation tolerance for horizontal equilibrium. Default is 5 degrees.

show

• angles (bool (True)) - Display angle deviations as dots on the edges of the FormDiagram and the ForceDiagram. Display of angle deviations are turned on by default.

• forces (bool (False)) - Display the edges of the ForceDiagram in a RGB gradient based on its length, and the corresponding edges in the FormDiagram are also displayed in the same color; red means longer edges (higher force magnitudes), blue means shorter edges (lower force magnitudes).

Solvers

tna

• horizontal.alpha (int (100)) - Default is 100 (or 'form100', meaning that the FormDiagram remains fixed and only the ForceDiagram will change during the Horizontal Equilibrium.

• horizontal.kmax (int (100)) - Number of iterations for the Horizontal Equilibrium solver. Default is 100.

• horizontal.refreshrate (int (10)) - Number of iterations to skip for the Conduit (dynamic drawing showing the iterations) during the Horizontal Equilibrium solver. Default is 10.

• vertical.kmax (int (300)) - Number of iterations for the Vertical Equilibrium solver. Default is 300.

• vertical.zmax (float (4.0)) - Default target height for the Vertical Equilibrium solver.

PatternObject

from_surface

• density.U (int (10)) - Number of divisions in the U direction of a surface for Create Pattern > From Surface. Default is 10.

• density.V (int (10)) .- Number of divisions in the U direction of a surface for Create Pattern > From Surface. Default is 10.

FormObject

ForceObject

ThrustObject

scale

• pipes (float (0.01)) - Global display scale factor for pipes.

• reactions (float (0.1)) - Global display scale factor for reaction forces at anchored vertices of the ThrustDiagram.

• residuals (float (1.0)) - Global display scale factor for residual forces at the non-anchored vertices of the ThrustDiagram.

tol

• pipes (float (0.001)) - Tolerance threshold for displaying pipes

• reactions (float (0.001)) - Tolerance for displaying reaction forces; if the reaction force is smaller than this value, it will not be displayed.

• residuals (float (0.001)) - Tolerance for displaying residual forces; of the residual force is smaller than this value, it will not be displayed.
