GfsOutputScalarStats

From Gerris

GfsOutputScalarStats is used to write the volume-weighted statistics over the whole domain of a given scalar.

The statistics are written using the following formatting:

DESCRIPTION time: T min: MIN avg: AVG | STDEV max: MAX

with:

DESCRIPTION

a description of the scalar field (without any spaces),

T

the physical time,

MIN

the minimum value,

AVG

the volume-weighted average value,

STDEV

the volume-weighted standard deviation,

MAX

the maximum value.

The syntax in parameter files is:

[ GfsOutputScalar ]

Examples

• "Garden sprinkler effect" in wave model

    OutputScalarStats { step = 12 } hs-MINLEVEL-NTHETA { v = Hs }

• Cyclone-generated wave field

    OutputScalarStats { step = 0.25 } hs { v = Hs }

    OutputScalarStats { step = 0.25 } vr { v = sqrt(U10*U10 + V10*V10) }

• Circular droplet in equilibrium

  OutputScalarStats { istep = 1 } {
    awk '{ print MU*$3/(0.8*0.8), $5, $7, $9, $11 }' > K-LAPLACE-LEVEL
  } { v = (K - 2.50771) }

• Axisymmetric spherical droplet in equilibrium

  OutputScalarStats { istep = 1 } {
    awk '{ print MU*$3/(0.8*0.8), $5, $7, $9, $11; fflush (stdout); }' > K-LAPLACE-LEVEL
  } { v = (K - 2.50771) }
