Dear Antii,
Thank you so much for your help. And, i'm sorry for being not able to provide you enough information so far. I've made some progress, by using a single INFLOW (HYDS) commodity as you can see on the pictures. I wonder if you have a look at on the attached screen capture of each process with their associated parameters. I hope this might be of help to figure out what is going wrong. I've also updated to ANSWER-TIMES 6.9.7.
Regards,
