The Post-Processor is common to all Cradle CFD software. It is used to visualize the data calculated by the solver. The Post-Processor is equipped with a multitude of functions such as contour, vector and values at specific points. The Post-Processor also includes may other high-quality graphical output functions.

Basic functions

Cradle's post-processor not only provides overall visualization effects but also provides precise information in critical regions to aid the engineering design process.

Other functions

Cradle's post-processor uses a variety of functions to visualize the calculation result both for CAE experts and the customer. Additional numerical information can also be acquired by further processing the calculation results.

Animation is an ideal way to visualize the flow. Cradle's post-processor can visualize both of steady-state and transient analysis by animation.

In Electronics Cooling, component temperature is a critical design requirement. However, during the design optimization process, knowing the flow of heat is instrumental for determining how the design should be modified to control the temperature. HeatPathView is a visualization utility in Cradle HEAT Designer electronics cooling analysis software and scSTREAM, structured grid general purpose CFD software, that enables engineers to manage heat dissipation at the component level and understand heat balances and heat paths in an intuitive graphical format. HeatPathView has three primary features.

  • First, the Part Temperature tab lists the maximum and average temperatures for the parts, the amount of heat generation, and the material name.

  • Second, the Heat Balance tab shows how much heat is dissipated from a component of interest and which other components receive this dissipated heat.

  • Third, the Heat Path tab shows the heat dissipation path for the component of interest. For example, it can show that heat flows from a component, into the air, into the board, and through the heat sink before being dissipated into the environment. This is very useful for determining whether a particular countermeasure is effective.
