• Version of VIC - VIC 5.0.1
• Name and version of the C compiler you are using - gcc 5.4.0
• Operating system - Ubuntu 16.04
• A description of relevant model settings - attached below

As the VIC only runs at sub-daily forcings, I used MetSim to disaggregate the daily forcings to 2-hourly. Now, when I am trying to run VIC at 120min timestep, the VIC output files have -nan values for the columns of OUT_EVAP, OUT_RUNOFF and for the 1st soil layer values of OUT_SOIL_LIQ and OUT_SOIL_MOIST. I can't figure out why. I have attached the global param file, a sample forcing file, and corresponding output file.

@shahryaramd -

When you say that you can't figure out why, what have you tried? Have you tried using a debugger to isolate when the nans are created?

@shahryaramd - Closing as we never heard back from you. Feel free to reopen if you are able to provide more information.

I actually was able to solve the problem. On changing the SOIL_QUARTZ value from -999 to a finite value solved it.
