scSTREAM - application of mathematical modeling of fluid dynamics and heat transfer problems with struktuirovannoy grid


Computational models in scSTREAM based on a simple and easy to construct a structured grid. The grid of this type consists of a plurality of small cuboids, so it approximates the curved surface only in the stepped structure.
Such nets embodiment is used in those cases where the curved surface or small parts do not significantly affect the overall result. Examples of application of the structured mesh are found in the simulation electronics cooling, heating, ventilation and air conditioning, as well as when designing architectural structures.
Features, functions and tasks specific to scSTREAM:
Various representation methods geometry
The shape model to be analyzed, can be represented using the following methods:
- Method voxel (inclined and curved surfaces are shown in cuboids);
- method beveled cells (specification model developed using CAD-systems);
- the finite element method (model arbitrary shape with an unstructured mesh can be applied to the model with a structured grid, which allows to use the model of the CAD-system to its original form).
Modeling the movement of objects
scSTREAM system allows to calculate flow generated absolutely rigid moving object. As conditions can be set such parameters as the movement of an object (movement, rotation, elastic deformation) generation / absorption of heat, the supply / removal of air. For a moving object model to create another grid. In this approach, conditions such as the distance traveled by the object, are not particularly limited, and it allows you to create models of arbitrary complexity.
Scaling of boundary conditions
If the test target phenomenon has a size on the order less amount of environmental influence him, the results of analysis of the environment can be used as boundary conditions in order to reduce the time and number of computations.
free surface
The software calculates the shape of the contact surface between the gaseous and liquid substance. This feature is useful in a wide range of fields: from analysis of a tsunami in the area of ​​civil engineering and construction to solder analysis in the field of electronics.
Calculation of high complexity models
When the grid structured complex model practically does not need to be adjusted, since the shape and size of the elements of the model does not affect the complexity of mesh. Furthermore, when parallel processing calculation is performed at high speed. This provides the efficiency of data processing.
Local mesh refinement
Milling can be carried mesh locally to more accurately represent the shape of the model and effective implementation of the calculation.
Create custom variables and scripts
Target complex conditions comprising trigonometric functions or branches with the IF statement can be executed without compilation.
Library of electronic components
The geometry and the properties of commonly used parts can be saved in a library for reuse in the future, which saves time when creating the calculation model.
Showing thermal path (HeatPathView)
Obtained in step postprocessing analysis results of CFD-temperature information of each part highlighted and a total amount of heat sufficient for understanding the thermal path. HeatPathView displays thermal path and the amount of heat transferred in the entire computational domain with the help of charts, graphs and tables, making it easy to find bottlenecks.
Import data from the CAD electronic devices
This function allows you to read and import the schema data wiring circuit board of the CAD-systems. This allows to obtain more realistic simulation result with the heat caused by uneven circuit wiring.
HeatDesigner module (included in scSTREAM distribution) is designed for a thermal design of electronic components
HeatDesigner - is a specialized solution based scSTREAM, which is designed for the thermal design of electronics. Performance HeatDesigner optimized for cases which do not require accurate reproduction curved geometry to predict the flow field. However HeatDesigner support grid consisting of more than one hundred million items, which allows sufficiently accurate to describe the small elements of geometry. As is the case with scSTREAM, HeatDesigner main advantages are a short calculation time and low consumption of computing resources.
