[BUG] Running image driver with Lakes/Wetlands causes Segmentation Fault

KMarkert commented 2 years ago

Overview

I am attempting to run VIC using the image driver and simulate lakes/wetlands. When executing the model, it is initialized and begins running the time steps, however, the model then crashes with a Segmentation fault. Since the model gets to running the timesteps it makes me believe the parameters are formatted correctly and the CHANNEL_IN forcings is defined (however still not completely sure about the formatting for the parameters). The model runs fine when not using lake/wetland model.

Model output with error

Compiler info

I am using the image driver so I believe the compiler is mpicc but including gcc info just in case.

$ mpicc -v     
mpicc for MPICH version 3.4.2

$ gcc --version
gcc (Ubuntu 9.3.0-17ubuntu1~20.04) 9.3.0

Lake parameters in global config

#######################################################################
# Lake Simulation Parameters
# These need to be un-commented and set to correct values only when running lake model (LAKES is not FALSE)
#######################################################################
LAKES  TRUE    # Lake parameter path/file
LAKE_PROFILE   FALSE   # TRUE = User-specified depth-area parameters in lake parameter file; FALSE = VIC computes a parabolic depth-area profile
EQUAL_AREA TRUE   # TRUE = grid cells are from an equal-area projection; FALSE = grid cells are on a regular lat-lon grid
RESOLUTION 39.0625   # Grid cell resolution (degrees if EQUAL_AREA is FALSE, km^2 if EQUAL_AREA is TRUE); ignored if LAKES is FALSE

I am happy to share any additional information to help debug the error. Thanks!

Closing as this was a user error. I tested running the model using the Findley Lake example data and model completed successfully.

Turns out that if the a grid cell defined as a lake runs out of water (lake depth = 0), it will provide the Segmentation fault error.

does this mean that vic cannot represent lakes that dry up? I am running the model with the classic driver, which allows me to see the results of the cells in which the model is executed for all times, as well as the cell in which the simulation is cut until the last available time. I was able to notice that the segmentation error occurred in the first cell in which basin_depth and depth_in (basin_depth*0.98) were less than 0.6 m, when channel_in = 0 (for all times), resulting in increased lake temperature, increased latent and sensible heat, decrease of the depth and area lake and finally the drying of the cell.
