Modifying and importing CAD geometry data
scFLOW Preprocessor interface is compliant with major CAD data. It allows user’s own geometry data to be directly imported for CFD analyses.
Various geometry editing functions are available, without having users modify CAD data specific for CFD analyses.
Extensive fluid property database
Over 120 fluid properties are available in scFLOW Preprocessor’s material property library, including incompressible/compressible gas/fluid.
- Gas (incompressible): 31 types
- Gas (compressible): 5 types
- Liquid (incompressible): 75 types
- Industrial lubricant by Idemitsu Kosan (incompressible):10 types
- Liquid (cavitation): 1 type
* Numerical data available for each property
- Incompressible fluid
Density, viscosity coefficient, specific heat at constant pressure, thermal conductivity, thermal expansion rate, surface tension coefficient
- Compressible fluid
Gas constant, viscosity coefficient, specific heat at constant pressure, and thermal conductivity
Compliant with CAD native format
scFLOW will efficiently accept major CAD such as Parasolid XT and STEP, high-end CAD such as CATIA, PTC Creo Parametric, and NX, and mid-range CAD such as SolidWorks, Autodesk Inventor, and Solid Edge and generate mesh based on the original geometry.
Robust model building using wrapping function
Parts of the analysis model can be created without any errors by wrapping multiple solid sheet parts. Although detailed sharp edges may be partially rounded by the process, this is an effective approach for users who encounter problems with CAD data conversion.
CAD data cleaning (geometry simplification)
CFD analyses often requires additional processes which are usually unnecessary in architectural design and structural analysis phases, such as ensuring no space between solid surfaces, deleting unnecessary parts (e.g. screw holes), or solidifying parts faultily recognized as sheets. scFLOW Preprocessor comes equipped with CAD editing functions that will significantly reduce workloads like these. Users would not have to go back to modifying CAD data unless a unique geometry is involved.
Modification, deformation, and relocation of CAD parts
CAD edit function not only simplifies complex geometry, but also is capable of applying thickness to a specific part surface, modifying geometry based on plane equation and such. Basic editing capability (solid and sheet) includes extraction of solid from solid holes and Boolean operation.
Creation of new CAD parts
scFLOW has capabilities normally employed in major CAD packages, such as creating primitive geometry from scratch and generating new parts by referring to existing parts.
