It is very short article about post-processing in FlowVision. Just main idea which allow you quickly build several ColoredFD pictures.

Layers and Characteristics

It  is possible to look on some integral characteristics or visualize distribution of some variable in computational space.

Characteristics – it is way to calculate some integral values which based on some variable. For example with characteristic is possible to calculate Flow rate, Integral forces and torques, averaged value of Pressure, Velocity, Temperature, etc. in volume or over surface.

Layers – it is distribution of vectors in volume or over surface, color contours over surfaces and in planes, streamlines and other visualizations of local values of different variables.

How to determine Characteristics or Layers

To create Characteristics or Layers it is necessary to make three steps:

  1. Specify HOW you want to visualize your variable (vectors, streamlines, integral characteristics)
  2. Specify WHERE you want to visualize your variable (in volume of some object or over surface of other object)
  3. Specify WHAT variable you want to visualize

How you want to visualize

Just create Characteristic or Layer (right click over Characteristic folder or Layers folder in Postprocessor tree)

For layers in next window is necessary to choose kind of layer:

Where you want to visualize

When you create Layers and Characteristics it is necessary to choose object which will used for calculating of visualization data.

You may want to color with pressure only part of your model or you may want to calculate averaged pressure only over part of model.

You can use next objects for visualization:

What variable you want to visualize

When you created layer or characteristic, choose it in project tree. In properties window you can make many thin customizations of layer. Here also is necessary to specify Variable which will be used for visualization.

What are features of FlowVision’s visualization?

There are several features which is important to know:
