Error when using sol200 for model updating

[benkra]

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!
