Restart Block¶

The restart block provides all settings required to continue a simulation from a previously saved state. It allows the solver to load solution fields, time information, and optional patch data from earlier runs.

Warning

This block is optional.

Flags Overview¶

Note

All flags and their description are included in the table below. A detailed description of which values are possible for each input flag follows.

Flag	Required	Description
`RESTART`	No	determines whether the simulation starts from a specific iteration defined in restart_tag
`RESTART_TAG`	No	specifies the iteration number from which the restart file should be read
`DINO_NEW_TIME_STEP`	No	determines whether to use a new initial time step from init_timestep (.true.) or the one in the restart file (.false.)
`READ_FROM_1D`	No	enables projecting a profile from 1D to higher dimensions (advanced use)
`TWOD_FROM1D`	No	enables projecting a 1D profile to 2D (advanced use)
`THREED_FROM1D`	No	enables projecting a 1D profile to 3D (advanced use)
`THREED_FROM2D`	No	enables projecting a 2D profile to 3D (advanced use)
`PATCH_SOLUTION`	No	determines whether to use a given flamelet table
`PATCH_ITERATION`	No	iteration number from which the patch file is read
`PATCH_SOL_FILE`	No	name of the patch file
