due to the epidemic I produced some eduational videos to show you the steps of building models in Processing MODFLOW.
You should know that these videos were made using tools we have and not using the abilities of professional studios. I am sorry for some aborted sentences, some loud barking of my dogs, boring parts, etc... I hope that the videos will serve the better understanding of modeling steps. All videos are converted and saved into the most compressed Matrjoska *.MKV format. You may use VLC or other codes to open them... I was using Processing MODFLOW version 8.0.47, but even using v5.3.3 you can do ther modeling tasks. I formulated the task always keeping in mind the limitations of the educational/demo version of PMWin 8.0 software.
Dowloading the videos is free to everyone... use it for your own risk on "as is" basis - even if they are not my students, not students, etc... I made them quite quickly so there might be some minor mistakes in it, but I hope that the general aim to help your studies is succeeded. I published all videos on google drive (see links below). Sorry for some missing explanation videos! For Hungarian speaking students please also visit the videos in Hungarian!
