本书基于Fluent 6.2.16版本、Gambit 2.2.30版本和Tecplot 10.0版本，共13章。全书首先详细介绍了Fluent软件及其相关的理论知识，然后通过典型的实例来讲解Fluent在传热、传质及流场等实际工程中的应用方法和技巧，包括运动部件的速度场模拟、UDF和UDS的使用、并行计算的设置、计算区域的绘制和边界条件的定义、Tecplot的数据处理等。每个实例都有详细的说明与详尽的操作步骤，读者只要按照书中的指示与方法操作，即可完成一个具体问题的数值模拟与分析，进而逐步掌握利用Fluent进行流体流动数值模拟的基本方法。 (Fluent 6.2.16 Based on the book version, Gambit 2.2.30 version and the version of Tecplot 10.0, Chapter 13. First of all, the book detailed the Fluent software and its related theoretical knowledge, and then through a typical example to explain Fluent in heat transfer, mass transfer and flow field, such as practical engineering methods and techniques, including the moving parts of the velocity field simulation, UDF and the use of UDS, parallel computing setting, rendering the calculation region and the definition of boundary conditions, Tecplot' s data processing. Each have a detailed description of examples with detailed steps, readers as long as the book' s instructions and in accordance with the method of operation, to complete a specific question of the numerical simulation and analysis, and gradually master the use of Fluent for numerical simulation of fluid flow of the basic method .)

西门子仿真编程软件S7-PLCSIM V5.4，用于S7-300/400系列PLC程序的仿真(S7-PLCSIM V5.4 offers the following new features with this release: DP, Industrial Ethernet and PC Internal connection types supported in addition to MPI Formerly, S7-PLCSIM used a default connection of MPI, address 2. With S7-PLCSIM V5.4, you can browse STEP 7 projects and select a networked node for establishing a simulation connection. S7-PLCSIM simulates the CPU of the selected node, all nodes that belong to that CPU, and the subnet of the selected node. Increased number of blocks supported for simulation S7-PLCSIM supports a set of OBs, SFBs, and SFCs as described in the electronic manual and online help. Of these, some are NOPs that is, they do not perform any operation. With S7-PLCSIM V5.4, the number of blocks that are not NOPs has increased.)
