What is Model Verification?

SimBiology has functionality that helps you find and fix warnings that you might need to be aware of, and errors that would prevent you from simulating and analyzing your model.

Model verification checks many aspects of the model including:

• Model structure

• Validity of mathematical expressions

• Dimensional analysis

• Unit conversion issues

When to Verify a Model

You can check your model for warnings and errors at any time when constructing or working with your model. For example:

• Verify your model during construction to ensure that the model is complete.

• Verify the model after changing simulation settings, dimensional analysis settings, or unit conversion settings.

Analyses such as simulation, scanning, and parameter fitting automatically verify a model.

Tip   Repeatedly running a task using a different variant or setting a different value for the InitialAmount property of a species, the Capacity property of a compartment, or the Value property of a parameter, generates warnings only the first time you simulate a model. Use the verification functionality described in this section to display warnings again.

Verifying That a Model Has No Warnings or Errors

Use the verify method to see a list of warnings and errors in your model.

Use the sbiolastwarning and sbiolasterror functions to return the last warning and last error encountered during verification.
