How to plot the Amplitude?

 hi

i used an Amplitude keyword in ABAQUS  and wanna plot it.

The keyword is *Amplitude, Definition=Bubble  (must be invoked in Keyword environment and is not available in CAE)

ABAQUS has built-in mechanical model  to simulate the radius and depth of bubble.

i need the two mentioned output data (radius and depth).

This paragraph is part of ABAQUS help about this simulation:

i checked that files after analyse but there is not any data about bubble simulation

i appreciate your helps

 " In an underwater explosion event a bubble migrates upward toward, and possibly reaches, the freewater surface. If the bubble migration reaches the free water surface during the specified analysis time, Abaqus applies loads of zero magnitude after this point.

Model data about the bubble simulation are written to the data (.dat) file. During an Abaqus/Standard analysis history data are written each increment to the output database (.odb) file.

The history data include the radius of the bubble and the bubble depth below the free water surface.  "
