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!
