I'm trying to run a simple simulation using doorTodoor DRT. My scenario includes 3 modes: pt, car, and drt. I keep getting the following errors at different iteration (1st or 3rd, or 30th, etc.) each time I run the simulation. I understand that there are some files missing but I don't understand why and why it happens at random iteration each time. I've attached my config file and Warnings&Errors file. I'd appreciate if anyone can give me some hints on what I'm missing that cause this error.

Thank you very much.

Hi Zahra,
it looks like there's some problem with writing the output data. There may be several reasons for that (perhaps your hard drive is full, or Windows has some access problems, just to name some).
In your config, could you try to disable both detailed output options? Especially the vehicle stats are creating a huge amount of data that is mostly unneccessary, whereas the Customer stats are generally more important.
<!-- Writes out detailed DRT customer stats in each iteration. True by default. --> <param name="writeDetailedCustomerStats" value="false" />
<!-- Writes out detailed vehicle stats in each iteration. Creates one file per vehicle and iteration. False by default. -->
<param name="writeDetailedVehicleStats" value="false"/>
If the problem persists, try switching paths to a different directory.
Bests,
Joschka

Thank you Joschka. Changing the directory solved the problem.
