MPAS-8.0.1 - Floating overflow - error (72)


New member
Dear all,

I am currently facing an issue while running the atmosphere_model component of the new MPAS-8.0.1. Approximately two weeks ago, our technical support team assisted me in successfully compiling MPAS-8.0.01 using Intel compilers and other necessary requirements, including parallel I/O.

However, my attempts to run the atmosphere_model at a 60 km uniform resolution have consistently resulted in the same error: “forrtl: error (72): floating overflow.” Despite compiling the model in debug mode, I have not been able to extract useful information regarding the root cause of this error.

More detail:
I have successfully executed the init_atmosphere step, generating all the initial conditions (,, and without encountering any error messages. The issue arises during the model integration phase when running the atmosphere_model using the outputs from the initialization step. In an effort to troubleshoot, I have experimented with modifying certain parameters in my namelist.atmosphere. For instance, I adjusted the config_dt from the usual 300 seconds (used with the 60 km mesh) to 360 seconds and even tested with 150 seconds, but unfortunately, the error persists.

Interestingly, the atmosphere_model ran successfully when I tested it with the supercell idealized case but will not run real-data. I have attached all the relevant namelist and stream files that I used for both the init_atmosphere_model and atmosphere_model.

Could you kindly provide any insights or guidance on resolving this issue? Your assistance would be greatly appreciated.
Thank you in advance for your time and expertise.

Best regards,
