[交流] 【求助】ANSYS 中命令流编程（fortran）已有11人参与

大家好，我是做焊接模拟的，用的是ANSYS软件。现在想做一段程序，其中想做个循环交替加载。
比如：载荷作用时间总共为10s，有两个载荷。
      其中，0-1s 给选定物体加载第一个载荷，
                  1-3s给选定物体加载第二个载荷
                  3-4s给选定物体加载第一个载荷
                  5-7s给选定物体加载第二个载荷
                  7-8s给选定物体加载第一个载荷
                  8-10s给选定物体加载第二个载荷
其实简单的可以这么理解。
但是我的载荷是一个由ANSYS函数编辑器定义的一个表载荷，
并且这两个载荷都是移动的。所以不清楚应该怎么用FORTRAN来编程。希望大家能给予帮助。定有回报。
下面就是我的命令流程序：

其中从双椭球热源加载到最后就是加载的过程，这是一个载荷，还需要另外一个载荷，这里没有加载，就像上面我所说的那样循环交替那样应该怎么加载，希望大家给予帮助。。应该用到怎么样的语句呢？？
