Dear Mariog,

Yes even i mean the same thing, IF ANY means -- if any vibrations are there send amplitude vs freq values.

The problem is solved, i made the nearby valve routing rigid and no question of freq and amplitude.

Thanks Mariog, PKU, and Richard for this help

For my knowledge sake, still iam in confusion abt these three statements

Can you please tell me.

1. if i run only static analysis, how to find amplitude value ?
2. if i run only modal analysis how to find amplitude value ?
3.if i run only dynamic analysis, how to find amplitude value, i think Max displacement in x,y,z ?
