General Module Function
The Read_TCF module is one of a limited set of Time_Data modules. These modules are specifically designed to create models and animations of data that changes over time. This type of data can result from water table elevation and/or chemical measurements taken at discrete times or output from Groundwater simulations or other 3D time-domain simulations.
The Read_TCF module creates a field using a Time Control File (.TCF) to specify the date/time, field and corresponding data component to read (in netCDF, Field or UCD format), for each time step of a time_data field. All file types specified in the TCF file must be the same (e.g. all netCDF or all UCD). The same file can be repeated, specifying different data components to represent different time steps of the output.
Read_TCF effectively includes an inter_time_step module internally in that it performs the interpolation between appropriate pairs of the files/data_components specified in the TCF file. Its internal structure only requires reading two successive time steps rather than the complete listing of time steps normally represented in a time_data field.
Module Input Ports
Read_TCF has one input port that accepts the current time.
Module Output Ports
Read_TCF has four output ports. From left to right:
The first port outputs the starting time.
The second port outputs the ending time.
The third port outputs the current time.
The fourth port outputs a normal field (mesh/grid plus data) representing the interpolated time step.
Module Control Panel
The control panel for Read_TCF is shown in the figure above.
The Read TCF File button allows you to specify the TCF file to read.
Click here for an example of a TCF fileand a description of the format.
The Date to Output is a type-in box that displays (or allows you to enter) the date and time for the interpolated time step.
The Display as Date toggle, if off displays the date as a number.
The Log Process Nodal Data toggle is used if the nodal data is log processed so that the interpolation is linear vs. geometric.
The Log Process Cell Data toggle is used if the cell data is log processed so that the interpolation is linear vs. geometric.
The cycle options are the same as those found in the loop module and an in depth help discussion can be found for them there.
