modelPipeWithScalarField
Visualizing a pipe with scalar field quantities along the pipe axis
Extends from Modelica.Mechanics.MultiBody.Interfaces.PartialVisualizer (Base model for visualizers (has a frame_a on the left side + outer world + assert to guarantee that the component is connected)).
Information
Model PipeWithScalarField visualizes a pipe and a scalar
field along the pipe axis. The latter is shown by mapping the 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 parameter "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.
Connector frame_a of this component is located in the center of the
circle at the left side of the pipe and the pipe axis is oriented
along the x-axis of frame_a, see figure below in which frame_a is visualized
with a coordinate system:
The color coding is shown in the next figure. It was generated with
MultiBody.Visualizers.Colors.colorMapToSvg
using the following call:
colorMapToSvg(Modelica.Mechanics.MultiBody.Visualizers.Colors.ColorMaps.jet(),
height=50, nScalars=6, T_max=100, caption="Temperature in C");
