GEOtop allows to pause a simulation at a given time step and then continue (recover) the simulation with the recovery option.
In geotop.inpts file there is a list of the recovery files: they are those inside the directory output/rec/ and begin with the letter "zo" and with keyword REC_...
In the option file, a block contains a list of the saving times expressed in days after the beginning of the simulation. When you reach the saving time (the first saving time is numbered 1, the second 2, and so on) the recovery files are created. An example of file name could be:
zo01_psi0001L0001.asc
where:
- zo01_psi is the name of the recovery file as written in inpts file
- 0001 is the ordering number of the saving point, i.e. saving point=1
- L0001 is the number of the layer, i.e. layer=1
This is the procedure to restart the model using the saving points:
- activate the recovery flag in the first block of ocontrol_parameters.txt (parameter 13)
- in the filename list (block 1 geotop.inpts) you should write the name of the files you want to use, including the suffix. For example if in the first simulation the name "zo01_psi" was written in the filelist name, the files zo01_psi0001 zo01_psi0002 etc are created. If you want to use the file zo01_psi0002 to restart a simulation, you have to write zo01_psi0002 in the list, and then the recovery files created in the second simulation will be named zo01_psi00020001 zo01_psi00020002 zo01_psi00020003 and so on
