model new command


model new <force>

Clear model-state information. Model information is cleared, allowing one to begin a new problem. The optional force keyword suppresses the model reset confirmation dialog (which will normally appear if the model has changed since the last save when the command is used).

Values associated with the project or program state are unaffected by the model new command. See the project new and program commands.

Model-state information includes any defined FISH functions and variables, histories, and tables.

The entire model state can be written to a file via the model save command for subsequent recovery via the model restore command. Alternatively, a FISH function can write data to a file (see File Utilities), and a different FISH function (created after the command is executed) can read back that data.


When running several different problems from a called file, the model new command must be given before each new problem.
