GfsEventSum

From Gerris

GfsEventSum computes the time-integral of a variable or function at each spatial position.

The syntax in parameter files is:

[ GfsEvent ] [ GfsFunction ] S

where S is the name of the variable where the integral will be stored.

Examples

• Collapse of a column of grains

    EventSum { istep = 1 } U SU

    EventSum { istep = 1 } V SV

• Turbulent air flow around RV Tangaroa

  EventSum { start = 1 istep = 1 } U SU

  EventSum { start = 1 istep = 1 } V SV

  EventSum { start = 1 istep = 1 } W SW

  EventSum { start = 1 istep = 1 } U*U SU2

  EventSum { start = 1 istep = 1 } V*V SV2

  EventSum { start = 1 istep = 1 } W*W SW2
