Simulink.fault.deleteAll

Delete faults and conditionals in models

Since R2025a

Syntax

Simulink.fault.deleteAll(model)

Simulink.fault.deleteAll(model,Name=Value)

Description

Simulink.fault.deleteAll(model) deletes the faults and conditionals in the specified model.

Simulink.fault.deleteAll(model,Name=Value) deletes the faults or conditionals using one or more name-value arguments.

Examples

Delete Faults and Conditionals in Model

Open the fault_analyzer_intro model.

openExample("faultanalyzer/FaultAnalyzerIntroExample")

Add two faults to the Sine Wave block.

model = "fault_analyzer_intro";
Simulink.fault.addFault(model + "/Sine Wave/Outport/1");
Simulink.fault.addFault(model + "/Sine Wave/Outport/1");

Add a conditional to the model.

Simulink.fault.addConditional(model,"myConditional","y1 >= 0");

Delete the faults and conditional from the model.

Simulink.fault.deleteAll(model);

Delete Only Faults in Model

Open the fault_analyzer_intro model.

openExample("faultanalyzer/FaultAnalyzerIntroExample")

Add two faults to the Sine Wave block.

model = "fault_analyzer_intro";
Simulink.fault.addFault(model + "/Sine Wave/Outport/1");
Simulink.fault.addFault(model + "/Sine Wave/Outport/1");

Add a conditional to the model.

Simulink.fault.addConditional(model,"myConditional","y1 >= 0");

Delete only the faults from the model.

Simulink.fault.deleteAll(model,Conditionals=false);

Input Arguments

model — Path or handle to model

string scalar | character vector | handle

Path or handle to the model, specified as a string scalar, character vector, or model handle.

Data Types: string | char | double

Name-Value Arguments

Specify optional pairs of arguments as Name1=Value1,...,NameN=ValueN, where Name is the argument name and Value is the corresponding value. Name-value arguments must appear after other arguments, but the order of the pairs does not matter.

Example: Simulink.fault.deleteAll("myModel",Conditionals=false) deletes only the faults from the model, myModel.

Faults — Whether to delete faults

true or 1 (default) | false or 0

Whether to delete the faults in the model, specified as a numeric or logical 1 (true) or 0 (false).

Data Types: logical

Conditionals — Whether to delete conditionals

true or 1 (default) | false or 0

Whether to delete the conditionals in the model, specified as a numeric or logical 1 (true) or 0 (false).

Data Types: logical

Tips

To delete only a specified fault or conditional, use the Simulink.fault.deleteConditional and Simulink.fault.deleteFault functions.

Algorithms

This function may delete the fault information file and fault model depending on how you specify the name value arguments:

Conditionals Setting	Faults Setting	Result
true	true	The function deletes the fault model and the fault information file.
false	true	If the model has conditionals, the function retains the fault information file but deletes the fault model. If the model does not have conditionals, the function deletes both files.
true	false	If your model has faults, the function keeps both files. If the model does not have faults, the function deletes the fault information file.
false	false	The function does nothing
