Model Execution Error - Simulation Aborted in Q2K Software

[Ульяна Романова]

Dear all, 

I am writing to get help with an issue encountered during the execution of a model simulation in the Q2K software environment.

The simulation terminated unexpectedly with the following error message:

*"is aborted! The program either crashed during integration or there was a problem during output. Try checking for bad inputs, using a smaller time step, Runge-Kutta integration, or adaptive time step integration, and running again. If that doesn't solve the problem, please report the problem to Greg Pelletier at gpe...@ecy.wa.gov and send a copy of the .q2k file for this run."*

In accordance with the error message instructions, I have attempted the following troubleshooting steps without success:

• Verified input data for potential errors or inconsistencies

• Reduced the simulation time step significantly

• Implemented both Runge-Kutta and adaptive time step integration methods

Despite these efforts, the error persists and prevents successful model completion.

I have attached the relevant .q2k and .out project files for this simulation run. They contain all input parameters, boundary conditions, and configuration settings used in the model.

I would be grateful for any insights you might have regarding potential causes or additional troubleshooting steps.

Thank you for your time and assistance.

Sincerely,

Uliana Romanova
