Example message
The value for Variable 'Coefficients' is not consistent with its domain specification because the value «null» is non-numeric
Cause
The domain for the indicated variable, Coefficients, specifies that Null values are not allowed in the result. This is specified by the «nullOk» parameter of the domain-specification function (one of the functions Continuous, Integer, GroupedInteger, or Discrete).
This is an advisory only -- intended to help you detect errors inadvertently introduced into your model.
By default, Null is usually tolerated in results. For this message to display, someone had to explicitly configure the domain attribute to explicitly disallow Null values. It thus seems likely that they did believed Null should never occur in a correctly functioning model.
Remedies
Since this was clearly configured to prevent Null, you or someone else has probably recently introduced changes into the model that may have introduced a mistake. The recommended course of action is to debug the source of the Null value, and correct the problem in the model.
To turn this off, you can re-configure the domain to allow Null values by removing the «nullOk» parameter from the domain (or setting it to true).
You can also disable bounds checking on the preferences menu.
