Large-Scale Analysis Capability
Speed-up of drawing involving large element division
The display speed of the element division in a large scale analysis of approximately 1 billion elements has increased up to 10 times that of the previous version. A video card supporting OpenGL 4.0 or later is required.
Optimization of cluster node
The distribution of memory consumption on a node-by-node basis has been optimized when computing with a cluster machine. High-speed calculation can be expected in simulations experiencing memory swap issues. Analysis with more number of elements can be performed in your current environment.
FLD file output by single precision
The size of the FLD file can be reduced to approximately 2/3 of that of the previous file output. This resolved the issue of when saving or transferring a large FLD file from large-scale simulations.
Enhanced Multi-phase Function
DEM(Discrete Element Method)
Heat transfer between particles and between particles and fluid can be calculated. Flow at a clogged filter can be considered.
Enhanced Multi-physics Function
Automatic Generation of Thermal Model for 1D-CAE
Heat path information generated by HeatPathView can be inherited to MapleSim. By using this function, itis possible to construct 1D-CAE model from 3D-CAD data and use it as multi domain heat transfer node.
New Feature of Postprocessor
Parts display and control similar to that in Preprocessor can be done in Postprocessor. This is effective when parts need to be control by inheriting the assembly structure or whenvisualappearance is most required.
New Features Dedicated to Electronics Field
Support for ECXML format
Thermal compact models made by semiconductor manufactures and data of other CFD tools can be imported. ECXML is an open file format that does not depend on a specific CFD tool and its capability is to be enhanced by JEDEC subcommittee.
Conversion into structure function
The simulation result can be converted to a structure function standardized by JEDEC standard (JESD51-14). A highly accurate thermal compact model can be created by fitting simulation results and the actual value of the semiconductor package.
New Features Dedicated to Architecture Field
Solar radiation absorptance considering the angle of incident
The incident angle dependent solar radiation can be considered. Postprocessor will reproduce so that the amount of solar radiation that passes through the window will be small when the incident angle is large, and vice versa.
scSTREAM is a general-purpose CFD tool that uses Cartesian or cylindrical structured mesh to enable easy mesh generation and high-speed simulations to be performed in a fraction of the time. Due to the meshing nature and analysis system that enables large-scale calculation, scSTREAM works best at processing extensive simulations, where users are required to solve thermal problems of electronic devices and indoor environment, wind flow, and heat island phenomena.scSTREAM thermo-fluid software has serviced the electronics and architectural industries for thirty years. The ever-evolving software is characterized by its overwhelmingly user-friendly interfaces and high speed processing.Spread of Virus in a Classroom - scSTREAM The shape of a model to be analyzed can be represented by using the following methods:
-Voxel method: slanted face and curved faces are represented in cuboids
-Cut-cell method: the shape of a model created with a CAD tool can be represented more accurately
-Finite element model method: a model of an arbitrary shape defined with unstructured mesh can be overlapped on a model defined with structured mesh to use the shape created with a CAD tool as is.Large scale calculation
In structured mesh, even a complicated model does not need to be modified almost at all and the shape or the scale of a model does not affect the difficulty of mesh generation. In addition, Solver performs a calculation at a high speed in parallel computing and achieves effective processing as the speed increases depending on the number of subdomains.Parts library
The shapes and conditions of frequently used parts can be registered. Conditions include the allocation position, material and heat generation.Heatpath view
The information on temperature of each part and a comprehensive amount of heat release obtained in post-processing of a general CFD analysis is not enought to know the heat path. HeatPathView displays heat paths and the amount of heat transfer in the whole computational domain in a diagram, a graph and a table, allowing you to find the bottleneck of the heat paths easily.Thermal confort, heat stress risk and ventilation efficiency indices
Confort indices PMV and SET* can be derived from already obtained temperature, humidity and MRT (Mean Radiant Temperature), as one of result-processing functions. WBGT (heat stress risk indices), and the scale for ventilation efficiency (SVE), of which some indices can be converted to a real time, can be set by one click and the range of calculation area can be selected (for example, either one of two rooms).Wind tool (outdoor wind environment assessment tool)
This tool helps assess outdoor wind environment. The assessment criteria can be selected from the ones proposed by Murakami et al. and by Wind Engineering Institute. By specifying a base shape and parameters required for wind environment evaluation, the parameters for 16 directions are calculated and the wind environment is ranked automatically. Detailed distributions of air current and pressure per direction can be visualized.Boiling / condensation
With the function, the user can analyze a boiling flow, which is a gas-liquid two-phase flow caused by temperature difference between a liquid and a heat conduction surface. A boiling flow is analyzed as a free surface analysis using MARS method, and latent heat generation and volume change due to bubble growth / condensation are considered using phase change model.ScSTREAM
