Displacement Controlled test using Boundry Condition Module in ABAQUS

Salam everyone,

I am working on Modeling of a Brick Wall Panel under reverse cyclic load with a concrete lintel at the top.

i need help regarding displacement controlled test in abaqus. there are a total of 24 cycles . . . first four cycles are force controlled (whose frequency is 1/60Hz) and the rest 20 are displacement control (whose frequency is 1/120Hz) . . . the following is the data file . . .

                            P R O B L E M   S I Z E

          NUMBER OF ELEMENTS IS                                 39366
          NUMBER OF NODES IS                                    45790
          NUMBER OF NODES DEFINED BY THE USER                   45790
          TOTAL NUMBER OF VARIABLES IN THE MODEL               137370

           VARIABLES. INCLUDE *PRINT,SOLVE=YES TO GET THE ACTUAL NUMBER.)

                              END OF USER INPUT PROCESSING

     JOB TIME SUMMARY
       USER TIME (SEC)      =   3.1000   
       SYSTEM TIME (SEC)    =  0.30000   
       TOTAL CPU TIME (SEC) =   3.4000   
       WALLCLOCK TIME (SEC) =          4

the problem is with the warning i am intercepting . . . please any one help me out with that . . .
