Hi
I am trying to run frequency analysis but i am getting 2 errors; Pls help out:
***ERROR: A PROCEDURE OPTION IS MISSING FOR STEP
LINE IMAGE: *BOUNDARY
***NOTE: DUE TO AN INPUT ERROR THE ANALYSIS PRE-PROCESSOR HAS BEEN UNABLE TO
INTERPRET SOME DATA. SUBSEQUENT ERRORS MAY BE CAUSED BY THIS OMISSION
*BOUNDARY
*NODE FILE, FREQUENCY = 0
*EL FILE, FREQUENCY = 0
*END STEP
***ERROR: STEP DEFINITION CARDS BETWEEN *END STEP AND *STEP ARE IGNORED. IF
MODEL DEFINITION KEYWORDS ARE DEFINED AFTER THE *END STEP KEYWORD
THEN THEY SHOULD BE MOVED TO THE MODEL DEFINITION PORTION OF THE
INPUT FILE. IF THIS IS A RESTART ANALYSIS CHECK FOR ANY UNSUPPORTED
MODEL DEFINITION KEYWORDS.

Hi Harnoor,
Assign5.inp has a boundary condition before the STEP which has a defined value, even though the value is 0.0. Any boundary condition that is defined outside a STEP can only be 0.0 because "events" can only occur in a STEP. I assume, therefore, that the Abaqus error occurs because of the BOUNDARY definition. This could either be moved into the STEP or converted into the following lines:
*BOUNDARY
Set1, 1, 6
