In the CMS-Flow [[SMS:CMS-Flow Model Control|''Model Control'']], the user can specify a previously saved hot start file to be used as initial conditions or instruct [[SMS:CMS-Flow|CMS-Flow]] to save hot start files for future use.

To create a hot start file, either select ''Write Hot Start output file'' and select an output time, or select ''Automatic recurring Hot Start file'' and choose an output interval.
 
*Choosing to write the hot start file at a specific output time will create the following file:
<blockquote>
*''hot_start.h5'' This file has the simulation data including elevations and velocities.</blockquote>
 
*Choosing automatic recurring hot start files will create the following files:
<blockquote>
*''HOTSTART.INFO'' This file records what time the hot start file was written and which hot start file is the most recent.
*''HOTSTARTx.H5'' (where "x" is a counter) These files have the simulation data including elevations and velocities. </blockquote>
 
Once the hot start files are created, they can be read into CMS-Flow. Open the ''CMS-Flow Model Control'' and check the "initial conditions file" check box, then select the hot start file to be used.
 
When using a hot start file, the following parameters should be changed as follows:
*''Start Date'': no change
*''Start Time'': no change
*''Simulation Duration'': decrease by the duration of the hot start file
*''Boundary Conditions'': no change
 
Note: For a simulation using a hot start file, the first time step of the solution will be the start time plus the value of one time step plus the duration of the hot start file.
