modelPipeWithScalarField
Visualizing a pipe with a scalar field
Information
Model PipeWithScalarField visualizes a pipe and a scalar
field along the pipe axis. 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 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.
The position and orientation of the center of the
circle at the left end of the pipe is defined via parameters
"r_0" and "R", respectively. The pipe axis is oriented along
the 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 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");
