I am currently working on a modeling project using MT3DMS and MODFLOW2005 due to the necessity of utilizing PHT3D. This requires me to use these older versions instead of the more recent MODFLOW6 with its GWF and GWT packages.

I have encountered an issue with outputting the budget data in MT3DMS. The output files from MT3DMS include UCN files and MAS files for different solutes. The MAS files only provide the total values for SOURCES and SINKS. However, I need to output detailed information for each boundary condition, such as WELLS, CHD, and RIVER, showing the solute sources and sinks at different simulation times.

In MODFLOW6's GWT package, this can be easily done using the OC module to set up a CSV file output. But I am unsure how to achieve similar functionality in MT3DMS.

Could anyone guide me on how to output a file in MT3DMS that includes the solute sources and sinks for each boundary condition separately at different simulation times?
