1184: Duplicate parameter/variable name

The error "Duplicate parameter/variable name" occurs. A parameter name or a variable name has at least two different definitions. For instance, the same variable name appears two or more times for a dependent variable,...

1183: Wrong number of DOFs in linearization point

The error "Wrong number of DOFs in linearization point" occurs. The current solution or the stored solution has for some reason the wrong number of degrees of freedom, sometimes due to a change of the implementation of...

1181: Circular function dependency detected

The following error occurs: "Circular function dependency detected." If you get this error, functions have been defined in terms of other functions in a chain. Check the user-defined functions in the model and make...

1180: Invalid degree of freedom name

The following error message appears: "Invalid degree of freedom name." COMSOL does not recognize the name of a degree of freedom. Check the names of dependent variables that you have entered so that they match the...

1171: Manual tuning of the Contact Pair condition.

In COMSOL 4.3b, the contact pair conditions were changed to improve manual tuning of the augmented Lagrangian contact formulation. In the augmented Lagrangian method, the penalty factor controls how “hard” the...
