General purpose thermo-fluid analysis system with structured mesh
Cradle v2020 is available today:
Integration with system modelling software is enhanced. Building on the open Functional Mockup Interface (FMI) integration already provided, Cradle now connects directly with more 1-D simulation tools. This enables customers to model complete products including electrical and mechanical subsystems in conjunction with the software’s built-in thermodynamics. Customers can easily map the heat transfer between electrical components using Cradle’s HeatPathView tool to visualize these multi-physics intractions. For example, providing optimization of heat routes in consumer electrical goods to enable system-level decision making with Maplesim or other 1-D simulation tools.
Introduced over thirty years ago, scSTREAM has serviced the electronics and architectural industries by providing high accuracy and high efficiency CFD solutions. During this time scSTREAM has mainly been characterized by its overwhelming user-friendly interfaces and implementation of a structured Cartesian mesh.
A structured mesh is simple, easy to construct, and fast to solve. This mesh is comprised of many small cuboids. It is most useful for applications where tiny details and surface curvature do not have a strong effect on the overall flow field. Applications that benefit from a structured mesh include: electronics cooling, HVAC, and architecture.
Wizard driven analysis conditions provide an easy to learn approach to setting up and performing a CFD simulation.
Using a structured mesh, models can quickly and easily be converted into a computational domain without the needed model preparation that is typical of an unstructured mesh.
scSTREAM uses a structured Cartesian mesh. Structured meshes are composed of many small cuboids, so it is very easy and quick to construct. In applications where attention to tiny details and curved surfaces do not have a strong effect on the simulation a structured mesh becomes very beneficial.
For a Cartesian mesh, each element face normal are aligned with the axis’s, making the calculation faster by reducing the number of calculations needed to determine the flux.
Flow generated from moving objects can be considered during translation, rotation, or elastic deformation of an object. The mesh of the moving object is created separately from the stationary mesh, this makes moving an object large distances computationally inexpensive.
scSTREAM interfaces directly with BIM 2.0 Autodesk® Revit® and GRAPHISOFT ARCHICAD. This allows for direct part targeting and the part tree can be kept and simplified. IFC format can be imported directly.
In addition to architecture there is a tool designed specifically designed to create precise electrical circuit components. After specifying design parameters, Electronic Parts Maker can consider various semiconductor packages such as: QFP, SOP, and BGA. Both Delphi and Two-Resistor modeling are also included.
