Question 
Is it possible to obtain the detailed processed data/flow conditions for 2D structures (e.g. culvert) from a MIKE 21 FM model?

Answer 
Yes, it is possible.  You can enable the output in the List and specify the output file on the Output tab, see example in Fig 1.

After the simulation, the information for each structure is stored in the model log file - see example in Fig. 2

For MIKE versions prior to Release 2021 you can manually enable the option by editing the .m21fm file with a text editor (such as notepad).
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. 3

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.
