abaqusDSA设计敏感性分析修改inp Solver Input File Processor？ 15
请教各位大佬，用dsa设计敏感度分析功能做悬臂梁敏感度分析，inp文件用记事本修改后提交，数据检查能过，但是然后立即出现solver input file processor exited with an error，修改了几次还是有问题。请教一下如何解决，谢谢！
悬臂梁inp文件如下百度网盘：

在dat文件里面的报错信息摘选如下，知道里面英文的意思但改了很多次还是没用，请教各位如何解决谢谢

后来发现关键字*Cload属下的参数<Pi>后面带了句点"."，可能是浮点参数<Pi>（查了帮助文档和辅导书籍说该参数必须是浮点数，可能我输入了整数程序自动转化为浮点数），浮点数小数点又与后面的句点"."混淆。inp文件此处的句点改为逗号","，即<Pi>.改为<Pi>,然后把前面"*PARAMETER Pi=-10000"的整数"-10000"改为浮点数"-10000.0"就可以顺利计算出结果了。
