How is the format of the contents in EFDC’s restart.inp/out represented? I am developing EFDC-related predictive applications and would like to modify the hydrodynamic result files based on actual conditions before continuing the simulation.
Is the restart.out file essentially representing the hydrodynamic results? However, the content of this file has no annotations, and I can’t understand it.
Hi paladinxueyizhu,
The restart.inp/out file is used for a hot start run in EFDC+. It represents a saved solution from a previous simulation at a specific time step as the initial condition. The initial condition here includes all dynamic conditions, including velocity fields, turbulence, and boundary conditions, exactly as they were at the previous simulation’s last time step.
For I/O operations on such a file, EEMS does not provide variable notations as it does in configuration files like efdc.inp. Modifying the information in the restart file may lead to inconsistencies in the model’s hydrodynamic behavior.
To understand the file structure, we recommend referring to the Fortran subroutine Restart_In(OPT) (starting from line 491) in the restart module (mod_restart.f90), where EFDC+ reads the file.
We also recommend considering the warm start option for modifying the hydrodynamics in the continuation run

Thank you for your response. The main issue is that during development, I want to use the previous hydrodynamic results as the driving force before running the model. At the same time, I want to adjust the initial field based on the observed water temperature values. The restart.inp hot start file definitely includes the hydrodynamic results, but does it also contain water temperature data? I want to locate the water temperature data, adjust it according to the observed values, and then run the model again.
