Hello Ashish,

Thank you very much for the reply. Actually, I am also using command object for applying some commonds repeatedly by using the method you told. But my question is how can I apply this method when I perform a coupled analysis involving transient structural and system coupling. Let me ask my question in another way. When I perform a coupled transient analysis, I am allowed to use only one load step in the Mechanical application, and the method you mentioned (use of 'step selection mode' for command object) works for more than one load step. In such case, how can I run the command object at various time steps within one load step. 

Thank you,
