All notable changes to AnaFlow will be documented in this file.

1.2.0 - 2025-10

added solutions based on the effective transmissivity for the “Integral” variogram model (#13):
- ext_thiem_int: steady state solution
- ext_thiem_int_3d: steady state solution incorporating vertical anisotropy
- ext_theis_int: transient solution
- ext_theis_int_3d: transient solution incorporating vertical anisotropy
added fix_T_well and fix_K_well bool flag to transient heterogeneous solutions to be able to set if the well value for the effective transmissivity/conductivity should be determined from the limit (True) or from the upscaled value in the first ring segment (False, default) (#13)
- breaking: the previous behavior was effectively this set to True, which for steep effective curves resulted in an increasing error in the effective head near the well
converted the grf_laplace solver to a Cython extension to improve laplace-space runtime and keep the Python API unchanged (#15)

updated docs (use myst parser for markdown files, only generate html and pdf)
updated CI (fixed artifacts up-/download action)
package now depends on Cython and is not system independent anymore but wheels are provided for all supported platforms and Python versions

See #11

the output for transient tests now preserves the shapes of time and rad (better for plotting in 3D)
the grf model is now the default way of calculating pumping tests in laplace space
the grf_laplace routine was optimized to estimate the radius of the cone of depression
the grf_laplace uses now the pentapy solver, so we get rid of the umf_pack dependency
grf_model and grf_disk are now part of the standard routines

the input for transient tests changed from “rad, time” to “time, rad” as order of input (in line with output format)
