求助结构优化问题!
请问大家一个结构优化的问题: 在PATRAN和NASTRAN 2005r2版本里面怎么生成约束反应(response)?我试着在卡片里面添加:DRESP1和DCONSTR项,但在计算的时候总是报错:
SYSTEM FATAL MESSAGE 3001 (DOPR3)
THE INPUT DATA BLOCK NAMED DIT AT POSITION 18 DOES NOT EXIST.
USER INFORMATION: THIS ERROR IS CAUSED BY ONE OF THE FOLLOWING:
1. THE DATA BLOCK WAS NEVER CREATED.
2. THE DATA BLOCK WAS DELETED.
3. THE DATA BLOCK IS SPECIFIED ON A TYPE STATEMENT IN THE CURRENT SUBDMAP OR A HIGHER SUBDMAP
BUT THE CURRENT QUALIFIER VALUES DO NOT MATCH
THE QUALIFIER VALUES OF THE DATA BLOCK(S) ON THE DATABASE.
求助高手指点,不胜感激! 问题已解决,谢谢大家的关心!
