Is it possible to obtain the detailed processed data/flow conditions for 2D structures (e.g. culvert) from a MIKE 21 FM model?
Yes, it is possible. There is a hidden feature within the MIKE 21 FM file (the .m21fm file needs to be opened with a text editor such as notepad) which allows the extraction of detailed flow conditions information (processed data) from structures. After initializing the simulation from the Launch Simulation Engine (please see the ‘Note’ below), the information for each structure is stored in the model log file - see example in Fig. 1
Fig. 1 - Information for each structure is stored in the model log file
To activate this option, the following parameter (‘print_data = 1’) needs to be inserted manually in the relevant data section within [STRUCTURE_MODULE] - see example in Fig. 2
Fig. 2 - (‘print_data = 1’) inserted manually in the relevant data section within [STRUCTURE_MODULE]
Note: the modified model setup needs to be executed using the Launch Simulation Engine. Using the normal model editor will delete the optional parameters from the input file.
