shell_sat_gasn#

EQ = shell_sat_gasn {Galerkin_wt} SH_SAT_GASN {Interpol_fnc} <floatlist>

Description / Usage#

This card provides the capability to solve the porous shell equation for the inventory of trapped gas in a closed pore shell simulation, viz. the EQ=shell_sat_closed. The equation tracks the inventory of trapped gas and accounts for the compression (ideal gas law) and dissolution into the invading liquid. Two terms are required in this equation:

shell_sat_gasn

Name of equation to be solved.

{Galerkin_wt}

Two-or four-character value that defines the type of weighting function for this equation, where:

  • Q1–Linear

  • Q2–Quadratic (not recommended at this time)

SH_SAT_GASN

Name of the variable associated with this equation.

{Interpol_fnc}

Two-or four-character value that defines the interpolation function for the variable SH_SAT_GASN, where:

  • Q1–Linear

  • Q2–Quadratic (not recommended at this time)

<float1>

Multiplier for the mass matrix term.

<float2>

Multiplier for the source term.

Examples#

Following is a sample card:

EQ = shell_sat_gasn Q1 SH_SAT_GASN Q1   1.0 1.0

This applies the equation with all terms activated.
