PowerCASE Overview

PowerCASE is a graphical tool that allows you to efficiently create, edit, and compile a complete PowerFLOW simulation case. It is the one and only tool capable of preparing a PowerFLOW simulation case. The compiled case file (.cdi) controls the construction of the simulation grid produced by the discretizer (PowerFLOW's grid generator), which in turn drives the actual simulation.

Key Features

Import facetized geometry in STL, NASTRAN, ANSYS, or PATRAN formats

Simple application of initial and boundary conditions and flow and simulation parameters

Quick and easy resolution region definition

Digital Wind Tunnel™ template for automated case setup

Integrated coupling with PowerCOOL and PowerTHERM

PowerCASE Geometry Viewer window (above, bottom) with model ready for PowerFLOW simulation. PowerCASE GUI tab (above, top), showing the summary of all geometric entities. Colors relate to displayed entities in Geometry Viewer window above.

Functionality

Import and position faceted geometry in STL (binary or ASCII), NASTRAN, ANSYS, and PATRAN formats.
Detect errors in faceted geometry during import and repair certain facetization problems.
Create and position simple geometry as a complement to importing geometry from a CAD system.
Specify or change the simulation model for the case. There are 32 available simulation models — permutations of each of the following options:
- Two-Dimensional vs. Three-Dimensional
- Internal vs. External flow
- Direct Simulation (for low Reynolds number cases) vs. Turbulence Modeling (for high Reynolds number cases)
- Heat Transfer vs. Isothermal
- Ideal Gas vs. Liquid
Specify the role played by each piece of geometry: solid region, fluid region, porous medium, heat exchanger, or in-line fan, as well as resolution, measurement, boundary condition, or non-inertial reference frame.
Define heat exchangers such as automotive radiators or charge air coolers
Define porous medium properties, such as those for radiators.
Define in-line fan model either by fan curve coefficients or supplier curve data table.
Define rotating reference frames for rotating geometry (e.g., fans or propellers).
Specify physical parameters of the fluid.
Use the built-in equation language to define parametric relations and time/space varying boundary conditions.
Visualize imported and created geometry.
Verify the completeness of your case. Generate the “compiled” version of the case file (with a .cdi extension) that will be used by the discretizer, the simulator, and PowerVIZ.
