Environmental Fluid Dynamics Code (EFDC) is a multifunctional surface water modeling engine that includes hydrodynamic, sediment-contaminant, and eutrophication components designed to simulate aquatic systems in one, two, and three dimensions.
Over the years, DSI has continued developing EFDC and into what is now known as EFDC+. To learn more about different versions of EFDC, please visit A Review of EFDC Versions - EEMS Blog
After you Prepare your environment.
Execute the following:
git clone https://github.com/dsi-llc/EFDC_Plus.git cd EFDC_Plus chmod +x toolkit-setup.sh
Run the setup script and pass in your package manager parameter (ubuntu users would use apt).
If you want to be able to compile the code, use option
If you just want to be able to run efdc, use option
toolkit-setup.sh <-r or -c> <package manager name> # example: toolkit-setup -r apt
Load the intel environment variables.
If your environment already has NetCDF installed and available in the Path, you can add the DNCOUT flag to the FFLAGS section in the makefile to compile with NetCDF features enabled.
make -f Makefile chmod +x efdc.x # this allows the built file to be executed as a program.
The run command structure is
cd /path/to/project mpiexec -n <number of nodes> path/to/efdc.x -NT<number of omp threads>
An example of a run command for a model with 4 mpi domains, running with 6 omp threads per domain (24 cpu cores total) would look like:
mpiexec -n 4 ~/code/efdc/efdc.x -NT6
Install Visual Studio:
Visual Studio Downloads
Clone the EFDC_Plus repository: https://github.com/dsi-llc/EFDC_Plus.git
Open the .sln file at the root of the repository.
If compiled with the NCOUT flag, you will need to get the NetCDF dlls to run EFDC+. The installer can be found here. Once installed, locate the bin directory (e.g. - C:\Program Files\netCDF 4.8.1\bin) and copy the dlls to your EFDC+ executable directory.
The open source availability of this code will make it easier for scientists, researchers, and developers to contribute to the code and build more trust in their models. We welcome all the opportunities to collaborate. If you would like to contribute to the source code development, please clone the repository and submit pull requests as needed.
