Thanks Dave,

The concept is clear for me now. And also, I have modelled the everything in a single file there wont be any issue for the timebeing.

But sometimes I have to work upon a some systems in isolation without proper input on whats there in connected system and that time I just get a bit puzzled as to how to simulate the end conditions at the connection points. But as you said I can follow any of the two approach of putting restraint and metioning F & M in results OR keeping the end free and mentionin displacements in the results.

Thanks.
