SetGuess
2D/3D

• SetGuess[rules] sets the current values of the system initial guesses. Guesses are given as a list of rules specifying the new values of the variables that are to have their current guesses changed.
• SetGuess[] restores all of the initial guesses to their default values as specified with SetBodies.

• SetGuess does not change the values of any of the permanent guesses set with SetBodies. Only the guesses that will be used for the very next solution attempt are changed.
• SetGuess accepts the SetParameters option to determine whether parameters in rules are used to change the values of system parameters. The default setting is SetParameters->False.
• SetGuess can be used to change the values of existing parameters with SetParameters->True, but not to introduce new ones; use SetParameters as a separate function call.
• See also: InitialGuess, LastSolve.

Further Examples

Load the Modeler2D package and define a simple model.

In[1]:=

Here the model is solved at . LastSolve returns the most recently found solution.

In[2]:=

Out[2]=

Out[3]=

If SetGuess is used to change specific initial guesses, the return value of LastSolve reflects the change.

In[4]:=

Out[4]=

Out[5]=

Here the guesses are all reset to the values specified with SetBodies.

In[6]:=
