Altair近几年的业务快速增长，一方面是工业在升级需求端旺盛，另一方面与它灵活的授权模式分不开。别的软件都是按套卖，Altair的软件按点数卖。差别在哪儿呢？Altair旗下有几十款常用的工业仿真软件（基本覆盖了企业需要用到的所有仿真需求），你同样的点数，既可以用A软件，也可以用B/C/D软件，买一赠几十，岂不美哉！比如，一般来说模型前处理工具HyperMesh都是要买的，比如你买两套，那就是42个点，这42个点可以允许你使用OptiStruct、Radioss这些求解器，还可以使用HyperStudy、HyperLife这些工具，企业何乐而不为呢！相对应的，如果你买了达索的Abaqus，你就只能用这一款软件，还需要额外再去配前后处理工具，那就花了两份钱了，况且，Altair的软件价格比达索实惠地多。
还有更狠的，单台电脑上Altair的软件点数不会叠加，只会取其中最高的。比如你电脑上，同时运行了HyperMesh（21个点），HyperView（21点），那统计点数就是21个点，如果这时候你又打开了OptiStruct计算求解（1-4核运行为30点），这时候点数占用就是30个点，也就是取你用的点数的最大值，这样就最大程度地减少了企业在软件上的投资。
Altair的软件授权模式
有三种，
- 单机版，很少用，除非客户只有一个工程师；
- 浮动版，最常见的授权模式，即一个中心服务器提供浮动license，多台客户端访问这个license服务器获取授权；
- Altair Managed License即由Altair帮你管理License，国内很少用，需要联网访问Altair服务器获得许可；
所以下面主要按第2中浮动版license的授权来说明。每个license文件（通常是*.dat格式）中，都会标明许可的点数信息。这个点数，就是官方说的Altair Unit。因为Altair旗下设计很多不同类型的软件，各自的Unit占比也不同，下面就最常见的情况说明。
结构分析优化的点数需求
先说1个工程师使用的情况
- 前后处理，HyperMesh/HyperView，占用21个点
- 分析求解，OptiStructFEA（FEA是Finite Element Method有限元分析方法的缩写），占用30个点（4核以内并行，如果更多点数要求会增加）
- 优化，OptiStructOPT（OPT是Optimization优化的缩写），占用50个点（4核以内并行，如果更多点数要求会增加）
即如果1个工程师只使用前后处理，那就买21个点，如果需要用到求解器，那就用30个点，如果同时要使用优化功能，那就要买50个点，所以对于一个工程师的公司来说，购买优化功能就显得不太划算。
那如果是3个工程师用呢，每个工程师至少需要21个点，那总共至少买63个点（21*3），那这样也就能使用50个点数需求的OptiStructOPT优化功能了，所以这就是Altair Unit这种销售模式的好处，一笔钱，用到了几倍的功能。通常来说，对于需要系统进行产品研发的公司，2~3人的配置是最基础最常见的。当然，一个工程师的电脑用了优化功能之后，别的两个工程师的电脑上就无法启动HyperMesh了，这点我们在下面电磁分析中举例说明。
电磁分析的点数需求
- 前处理，HyperMesh，占用21个点
- 电磁求解，Feko，占用30个点（4核以内并行）
所以如果一个工程师，就需要买30个点。但是两个工程师，只需要买42个点，也能使用前处理和求解，需要注意的是，求解的时候因为已经占用了30个点，所以现在池子中只剩下了12个点，此时另一台电脑如果打开HyperMesh就会提示点数不足（因其需要21个点）。也就是说，如果只买42个点，那要么是两个工程师同时只使用前处理功能，而如果如果工程师A用到了Feko求解，那就只能允许A开前处理，B就不能开前处理。这类问题可以在工程师人数较多（5人以上）的时候避免，因为不是每个工程师都需要时时刻刻开着HyperMesh。
Altair Unit点数的基本原则
从上面的说明中，可以看到点数计算的一些规律
- 不同软件的点数要求不一样
- 购买的点数是一个总池子，每台电脑需要使用软件的时候去这个池子里面取点数
- 单台电脑可以开多个软件，只取最高值，不叠加（这一点很重要，用好了可以节省很多点数，欢迎联系博主咨询方案）
- 不同电脑使用，点数会叠加
- 工程师越多，平均点数需求越小，每个人的软件投入就越划算（另一方面，总体点数多了，相应也会有更多折扣）
