Output Group File Specification For large grids or long simulations, outputting all of the variables to a single XMDF solution file can lead to a file that is unmanageable. To help reduce to the size of the output files each variable group listed in Table 54 can be output into separate files. The table below lists and describes the CMS-Flow cards used to specify the output file names for each variable group.
table 2-110
Advanced Global Output In addition to the variables specified in the SMS interface, CMS has the option to output advanced mode output including the bed shear stress, bed composition, wind speed, etc.

XMDF File Compression The standard CMS-Flow output is written to an XMDF file with the name <Case Name>_sol.h5. The binary file may be written in compressed for-mat using the card described in the table below.
table 2-112
ASCII Files In addition to the XMDF output file, CMS-Flow provides the output two types of ASCII output files: 1. Tecplot snap shot (*.dat), and history files (*.his) 2. SMS Super ASCII files (*.sup, *.xy, *.dat) The CMS-Flow cards used for outputting these two types of files are described in the table below.
table 2-113
Observation Cells (Save Points) Time series at selected Observation cells is set in the Cells tab of the CMS-Flow Model Control window. A description of CMS-Flow cards used for specifying Observational cells are described below.

Simulation Statistics CMS V4.0 has the option to calculate statistics over the whole model do-main for a user-specified time period. This option is accessed using the advanced cards. The starting time, end time, and time interval should be specified in hours with respect to the model start time. The time interval should be larger or equal to the hydrodynamic time step. When activated the statistics are written to the XMDF Global Solution File in a subfolder named stats. The CMS-Flow cards related to the statistics are described below.
table 2-115
Notes: • The units of the starting time, end time, and interval are hours. • If the interval is not specified, the initial time step is used as the interval.
A description of the hydrodynamic, sediment, salinity statistics is provided in the tables below.
