A system and method is provided that facilitates solving and enforcing associative constraints across heterogeneous models of the same system. The system may include a processor configured to: access an expression that specifies a relationship between at least one first constraint variable and at least one second constraint variable; access a first constraint map that maps at least one first model property of a first model to the at least one first constraint variable; and access a second constraint map that maps at least one second model property of a second model to the at least one second constraint variable. The processor may also be configured to: retrieve based on the first constraint map, at least one first model value of the at least one first model property from the first model by accessing a first modeling software component that is configured to access and manipulate the first model; and determine at least one second model value for the at least one second model property of the second model, based on the at least one first model value, the expression, the first constraint map, and the second constraint map.
