COMSOL 6.4 - For, EndFor

Add for loops to a solver sequence.

model.sol("sol1").create("for1", "For");

model.sol("sol1").create("endfor1", "EndFor");

model.sol("sol1").create("for1", "For") adds the start of a for loop.

model.sol("sol1").create("endfor1", "EndFor") adds the end of a for loop.

Use For and EndFor to enclose a sequence of solver commands that you want to iterate in a for loop. You can add more than one for loop, but they must be balanced so that each For ends with a corresponding EndFor.

You control the number of iterations in the loop using the following properties:

Table 6-34: Properties for the For Loop.
Property	Value	Default	Description
control	String	user	Name of the controlling study step or user if the feature is controlled manually.
expr	String	1	Global expression used to compute relative error when method=convergence.
iter	Positive integer	5	Number of iterations of the solver loop when method=iterations.
maxiter	Positive integer	25	Maximum number of iterations in the solver loop when method=convergence.
method	convergence \| iterations	iterations	Choose whether termination of the solver loop is based on the convergence of a global variable or a fixed number of iterations.
miniter	Positive integer	1	Minimum number of iterations in the solver loop when method=convergence.
rtolterm	Positive real number	0.001	Relative tolerance for termination of the solver loop when method=convergence.
rtolthresh	Positive real number	1	Threshold used to avoid division by zero while computing the relative error when method=convergence.
