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 . . .

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