Modelica.Mechanics.MultiBody.Visualizers.Advanced.SurfaceCharacteristics.torusFunction defining the surface characteristic of a torus
Function torus computes the X, Y and Z arrays to visualize a torus with model Torus. The left image below shows a torus with ri=0.5 m and ro = 0.2 m. The right images below shows the torus with the additional parameter settings:
opening = 45 degree startAngle = -135 degree stopAngle = 135 degree

Modelica.Mechanics.MultiBody.Visualizers.Advanced.SurfaceCharacteristics.pipeWithScalarFieldFunction defining the surface characteristic of a pipe where a scalar field value is displayed with color along the pipe axis
Function pipeWithScalarField computes the X, Y, Z and C arrays in order to visualize a pipe and a scalar field along the pipe axis with model PipeWithScalarField. The latter is shown by mapping scalar field to color values with a color map and utilizing this color at the perimeter associated with the corresponding axis location. Typically the scalar field value is a temperature, but might be also another quantity. Predefined color maps are available from MultiBody.Visualizers.Colors.ColorMaps and can be selected via input argument "colorMap". A color map with the corresponding scalar field values can be exported as vector-graphics in svg-format with function MultiBody.Visualizers.Colors.colorMapToSvg. An example is shown in the next figure:
The color coding is shown in the next figure. It was generated with Mechanics.MultiBody.Visualizers.Colors.colorMapToSvg using the following call:
colorMapToSvg(Modelica.Mechanics.MultiBody.Visualizers.Colors.ColorMaps.jet(),
height=50, nScalars=6, T_max=100, heading="Temperature in C");
