PipeWithScalarField
Visualizing a pipe with a scalar field
Library
Modelica/Mechanics/MultiBody/Visualizers/Advanced
Description
Model PipeWithScalarField visualizes a pipe and a scalarfield along the pipe axis. The latter is shown by mapping scalarfield to color values with a color map and utilizing this colorat the perimeter associated with the corresponding axis location.Typically the scalar field value is a temperature, but mightbe also another quantity.Predefined color maps are available fromMultiBody.Visualizers.Colors.ColorMapsand can be selected via parameter "colorMap".A color map with the corresponding scalar field values can be exportedas vector-graphics in svg-format with functionMultiBody.Visualizers.Colors.colorMapToSvg.The position and orientation of the center of thecircle at the left end of the pipe is defined via parameters"r_0" and "R", respectively. The pipe axis is oriented alongthe x-axis of the local coordinate system described by "R",see figure below:
The color coding is shown in the next figure. It was generated withMultiBody.Visualizers.Colors.colorMapToSvgusing the following call:
colorMapToSvg(Modelica.Mechanics.MultiBody.Visualizers.Colors.ColorMaps.jet(), height=50, nScalars=6, T_max=100, caption="Temperature in C");
