SysML can be integrated with other languages such as Modelica with the following process:

1. Create a metal-model for the specific domain that is being integrated. This could be done with the use of an ontology.
2. Create a SysML profile that will map the meta model to SysML stereotypes
3. Create a transformation map between the meta model and SysML profile's entities
4. For each transformation include the corresponding API call to the domain specific tool

There are two mainstream methods of transformation between two meta-models: Triple Graph Grammars (TGG) and Queries/Views/Transformations (QVT).

An example of using TGG to map between SysML and Modelica ¹⁾).

Modelica has emerged as a standard or modeling continuous dynamics of systems. Johnson²⁾ explores synergies between SysML and Modelica at 3 different levels:

1. Definition of continuous dynamics models in SysML;
2. Use of triple graph grammar to maintain a bi-directional mapping between these SysML constructs and Modelica models in order to maintain consistency;
3. Integration of simulation experiments with other SysML constructs to support MBSE.

SysML benefits from the detailed Modelica semantics for representing Differential Algebraic Equation systems combined with discrete events; Modelica benefits from the broader information modeling context provided in SysML.
