Error when using sol200 for model updating

Error when using sol200 for model updating

Error when using sol200 for model updating

(OP)
Hi guys,

we are trying to update the young's modulus of a simple structure with experimental frequencies using sol200.
However there is one error message remaining that we can't solve:


 *** SYSTEM FATAL MESSAGE 3001 (DOPR3)
     THE INPUT DATA BLOCK NAMED DYNAMIC  AT POSITION     19 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.
     USER ACTION: 1. IF YOU ARE EXECUTING AN MSC.SOFTWARE SUPPLIED SOLUTION SEQUENCE AND NOT USING THE
                     ALTER EXECUTIVE CONTROL STATEMENT, THEN CHECK FOR BULK DATA AND/OR CASE CONTROL INPUT
                     ERRORS. IF NO ERRORS CAN BE FOUND, THEN CONTACT MSC.SOFTWARE CLIENT SUPPORT.
                  2. IF YOU ARE EXECUTING A DMAP PROGRAM NOT SUPPLIED BY MSC.SOFTWARE, THEN FOR DEBUGGING PURPOSES
                     INSERT STATEMENT DIAGON(20) BEFORE THE MODULE SHOWN ABOVE.
     PROGRAMMER INFORMATION: THE FIST NUMBER IS    119 AND SUBROUTINE IS DOPR3


The code is also included below as a file:

The .bdf file works well with sol103 calculations and has about 4000 lines.
We would very much appreciate your help!
