[b] STAR-LT includes [/b] 1. Pro Modeler: with CAD construction function and using ICEMCFD as its automesh core; Can quickly construct models, set boundaries, generate grids, and perform post-processing; Most of the analysis can be completed in Pro modeler. 2. Pro LT: has an interface similar to STAR-CD and can use STAR-CD instructions and panel functions; Using bloack to construct an indispensable tool for mesh; In this interface, a more advanced setting menu is provided. 3. Pro MGR: It uses the same solver as STAR-CD and has the same solving ability. Currently, 2005 SR-1 has been officially released and used since January 2006; Some of the new features include the addition of blower fans and non isotropic heat transfer [b] Features: [/b] vivid solid modeling function adaptive mesh growth, rich mesh types, advanced Boundary layer mesh technology CAD interface format except STEP, SAT, IGES, DXF format files. Can also accept IDEAS, PATRAN, ANSYS, NASTRAN grid files· The Windows operation interface is simple and easy to learn. In addition, the analysis results can be output in many ways, such as graphics, text and data. The parameter settings are clear and clear. The physical properties are rich and complete, and users can edit relevant physical properties as required. It has various analysis functions, such as Non-Newtonian fluid analysis, thermal analysis, Natural convection, radiation, sunshine, diffusion, heat exchanger and filter model analysis (typical). Regarding the cooling problem of electronic machines. STAR-LT can provide effective model (typical) functionality· The parameters can be changed at any time during the calculation process, and the results are accurate and reliable [img] http://www.cdaj-china.com/product/star_lt/images/starlt_2l.gif [/img] [b] Large indoor environment heat flow analysis examples [/b] [b] And STAR-LT has a unique attraction [/b]. The biggest advantage of STAR-LT is its Pro Modeler module. Pro Modeler belongs to the design enabler, which reads standard CAD formats or CATIA files directly, and quickly fixes errors in the CAD file transfer process through CADfix. Its first build first win object construction principle eliminates the need for users to make differences on overlapping objects, This feature is not seen by other CFD software, and Pro Modeler has great flexibility in model construction and material library. Its grid generator uses ICEMCFD as the core, which is intuitive and easy to learn for engineers to quickly construct models with given heat source, rotation, porosity, and boundary settings. Therefore, Pro Modeler is quite helpful in preprocessing. The parameterization and scheduling solution built into STAR-LT in the solving part are also a major feature. If one of the boundary pressures needs to be given 5, 10, and 15 pa, generally speaking, it is necessary to set three models separately. However, in Pro LT, parameterization settings can be directly set, and it will automatically be divided into three models for analysis [b] The main new features of the new version of STAR-LT 2005 are: [/b] 1 Automatically generate an analysis case when a new file is opened, where users can determine the units and solve for the type (steady, Trailent) at the beginning of model construction. 2. Fan: Simple FanSTAR-LT has provided a direct P-Q curve acceleration simulation method for axial flow fans in the past, and in STAR-LT2005, a P-Q curve setting that conforms to the dual inlet centrifugal fan has been added, providing users with a fast setting analysis model and more accurate analysis results. 3. MRF: Simulation of a real fan in a multi rotating frame reference, which can truly reflect the characteristics of the fan. In addition, obtaining MRF from P-Q curves is an indispensable function. STAR-LT 2005 directly provides an interface for setting MRF in Pro Modeler, allowing users to solve directly without the need for Pro LT settings. 4. The automatic determination of the length scale of boundary conditions generally requires skill in determining the turbulent properties on the boundary when solving turbulence. However, in Pro Modeler 2005, the appropriate length scale for this boundary was automatically calculated. 5. Update CAD-interface Pro Modeler 2005 to include files that can be read into CATIA V5 version (optional). The support version for Parasolid format has also been upgraded to version 15. 6. In addition to the powerful CADfix function in the update grid generator Pro Modeler, its humanized model construction method is built first, wins first, and does not require the use of differencing in repeated object volumes, allowing users to quickly construct models. And its grid generator uses ICEM-CFD as the core, which does not have to endure the complex ICEMCFD interface, but can enjoy the fast and powerful grid generation function. The core of version 5.1 can generate grids more quickly. In Pro Modeler 2005, Hexa, Tetra, Hybrid, and Cartesian can be produced. Pro Modeler 2005 can save half of the grid generation time. Version time: Pro Modeler 2005 04:06 secPro Modeler 2003 08:57 sec7 Due to the development of composite materials, the heat transfer coefficients of some materials vary in various directions. The non isotropic heat transfer solution provided by STAR-LT 2005 can be more elastic and in line with the characteristics of composite materials or heat pipes widely used in the electronics industry. 8. Adjusting the relaxation coefficient in the solution can help accelerate convergence and avoid numerical problems. The function of adjusting the Relaxation factor can be enabled in the solution settings here.
