SolidWorks二次开发 API-SOLIDWORKS Simulation分析参数修改

今天我们来讲个小例子。
是关于SOLIDWORKS Simulation的。
先说明一点，这东西我也不熟。有问题别问我

首先，我做了一个很难的分析，条件也是很复杂，具体操作我就不说了，分析结果如下:

当然这个图和我们今天要做的事情 关系不大，我们主要了解 一下如何连接到SOLIDWORKS Simulation 上并修改载荷参数，重新运行分析，得到新的结果 。
具体的api查找过滤和之前看帮助类似，我就直接上图了:

下面是关键代码:
把上面的力的大小从100 改成150，然后重新进行风格的划分，运行计算。

这样结果出来了，至于怎么拿到最新的结果 ，或者说截图的话后面有机会再讲了。
