Whats the difference with running my model in iModflow and Standard Modflow

I don't see in the manual a good description of what the key differences are between running my model in iModflow and Standard Modflow2005 (both within iMod GUI) in terms of its implications for other functionality in iMod such as the use of various solvers (PKS), subdomain modelling or packages.Is there a preference for either approach and are there specific benefits with one approach over the other.RegardsGerry

Hi Gerry,iMODFLOW (which is MODFLOW2005 as well) does scale and clip datafiles inside the computational code, as running with standard MODFLOW2005, for which iMOD export default MODFLOW2005 packages, the scaling and clipping is done by iMOD. So, option 1 start running quicker as there is no need to export everything beforehand, as option 2 starts later, but in the end might finish quicker as the scaling and clipping is done more efficient by iMOD. Another advange for option 2 is dat all MODFLOW2005 (*.ARR) files can be inspected in iMOD to see how the scaling and clipping was performed. On the other hand, the PKS (Parrallel Solver) is only support for option 1 as the PKS uses the clipping and scaling features for defining the submodels. Speaking of submodels, that can be done with MODFLOW6 and steered from iMOD as well. So, hopefully this helps, but there is no need to make a choice, as all options (including MODFLOW6) can be selected prior to the start of the simulation.Regards,
