预应力求解问题
|
|
问题是这样的，我现在要做激光器封装应力应变分析，先进行回流，在回流求的形变和应力的基础上在求解激光器工作时候的应力和应变。单独进行回流和单独进行工作的都做过，都没问，但是现在整合到一块就各种报错，现在有一个问题，程序跑不下去了，错误日志的提示是这样： *** ERROR *** CP = 143.209 TIME= 21:08:24 The size of the displacement vector in the .ESAV file is 27914. It does not match with the size of the displacement vector in the current analysis which is equal to 83742. Please send the data leading to this operation to your technical support provider, as this will allow ANSYS, Inc to improve the program. *** ERROR *** CP = 143.677 TIME= 21:08:58 File file.mode does not exist. 我的命令流是这样的，建模和网格就不放了，因为模型是最简化的用来测试求解代码能不能运行的，所以网格很粗陋，错误很多（已经2000多K了错误日志），不过我觉得应该不影响后面求解命令的执行。求解命令： *** ERROR *** CP = 143.209 TIME= 21:08:24 The size of the displacement vector in the .ESAV file is 27914.

新出来的两条错误信息，是接在那两个信息之后的 *** WARNING *** CP = 149.090 TIME= 09:43:57 SOLVE is not a recognized BEGIN command, abbreviation, or macro. This command will be ignored. *** WARNING *** CP = 149.636 TIME= 09:44:02 The current solution may have been produced using different model or boundary condition data than is currently stored. POST1 results may be erroneous unless you perform a new solution using the stored data. |
