- K_CG_error(err, cond_gmean, var, len_scale, anis, K_well='KH', 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:
K_CG()
- Parameters
err (
float
) – Given relative error for the farfield conductivitycond_gmean (
float
) – Geometric-mean conductivity.var (
float
) – Variance of the log-conductivity.len_scale (
float
) – Corralation-length of log-conductivity.anis (
float
) – Anisotropy-ratio of the vertical and horizontal corralation-lengths.K_well (string/float, optional) – Explicit conductivity value at the well. One can choose between the harmonic mean (
"KH"
), the arithmetic mean ("KA"
) or an arbitrary float value. Default:"KH"
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
