iMOD Python 1.1.0

iMOD Python 1.1.0 is released 🎂

We are happy to announce the release of iMOD Python 1.1.0 🎉. The focus of this release was to improve the functionality to work with existing iMOD5 models, in collaboration with the “Kernteam Transitie NHI” 🤝.

🛠️ This release fixes over 20 bugs and contains new improvements 🛠️, including:

• Directly regridding iMOD5 databases into MODFLOW 6 simulations with the new target_grid argument in imod.mf6.Modflow6Simulation.from_imod5_data().
• Added imod.mf6.HorizontalFlowBarrierResistance.from_imod5_data() to load barriers from 3D GEN files.
• Added ignore_time_purge_empty argument to imod.mf6.Modflow6Simulation.mask_all_models() and imod.mf6.Modflow6Simulation.clip_box() to consider a package empty if its first time step is all nodata. This can increase performance a lot when working with models with many timesteps.

For the NHI collaboration, we furthermore developed a tool to help with the transition from iMOD5 to MODFLOW 6, which has a similar interface as iMOD5’s iMOD BATCH “RUNFILE” function. It can be found here and is a useful aid to transition from an iMOD5 model to iMOD Python.

This doesn’t end the work with the NHI collaboration, as we are still working on implementing some remaining iMOD5 features, like the sprinkling from IPF files. But since so many things have been fixed and improved, we decided to release this version now.
