anaflow.tools.coarse_graining.T_CG_error
- T_CG_error(err, trans_gmean, var, len_scale, T_well=None, prop=1.6)[source]
Calculating the radial-point for given error.
Calculating the radial-point where the relative error of the farfield value is less than the given tollerance. See:
T_CG()
- Parameters
err (
float
) – Given relative error for the farfield transmissivitytrans_gmean (
float
) – Geometric-mean transmissivity.var (
float
) – Variance of log-transmissivity.len_scale (
float
) – Correlation-length of log-transmissivity.T_well (
float
, optional) – Explicit transmissivity value at the well. Harmonic mean by default.prop (
float
, optional) – Proportionality factor used within the upscaling procedure. Default:1.6
- Returns
rad – Radial point, where the relative error is less than the given one.
- Return type
