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. Variable group output file name specification.

Card Arguments Default Description
WSE_OUT_FILE Character none Specifies the XMDF output file name for the water level group
VEL_OUT_FILE Character none Specifies the XMDF output file name for the current velocity group
EDDY_VISCOSITY_OUT_FILE Character none Specifies the XMDF output file name for the eddy viscosity group
VISC_OUT_FILE Character none Specifies the XMDF output file name for the eddy viscosity group (same as card above)
TRANS_OUT_FILE Character none Specifies the XMDF output file name for the transport group
MORPH_OUT_FILE Character none Specifies the XMDF output file name for the morphology change group
WIND_OUT_FILE Character none Specifies the XMDF output file name for the wind group

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.

Table 2-111. Advanced output datasets.

Card Arguments Default Description
WIND_OUT_TIMES_LIST integer 0 Output time series id for wind velocity and magnitude in m/s.
STRESS_OUT_TIMES_LIST integer 0 Output time series id for mean bed shear stress in Pa.
WAVE_OUTPUT_DETAILS ON

OFF

OFF Outputs additional wave variables including wave direction, radiation stresses, breaking dissipation and roller energy.

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. CMS-Flow card for compressing the XMDF output file

Card Arguments Default Description
XMDF_COMPRESSION ON

OFF

OFF Compresses the XMDF file

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. CMS-Flow cards used to output Tecplot and SMS Super ASCII

Card Arguments Default Description
GLOBAL_TECPLOT_FILES ON

OFF

OFF Outputs Tecplot ASCII files
GLOBAL_SUPER_FILES ON

OFF

OFF Outputs Super ASCII files

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.

Q_TRANS_OBS_CELLS_BEGIN none Marks the beginning of a Transport Observation point list.
Q_TRANS_OBS_CELLS_BEGIN none Marks the end of a Transport Observation point list.


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. CMS-Flow cards related to output statistics

Card Arguments Description
GLOBAL_STATISTICS [start time] [end time] [interval] Turns on the statistics for hydrodynamics, sediment transport, and salinity.
FLOW_STATISTICS [start time] [end time] [interval] Turns on the statistics for hydrodynamics transport.
SEDIMENT_STATISTICS [start time] [end time] [interval] Turns on the statistics sediment transport.
SALINITY_STATISTICS [start time] [end time] [interval] Turns on the statistics for salinity.

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.
