Sparx Systems has integrated a link with OpenModelica open source project to simulate and create graphs on SysML parametric models in its upcoming version 13, currently available in a beta preview.
This feature requires installing OpenModelica tool (https://www.openmodelica.org/). Algorithms must be entered in SysML constraint blocks as invariant constraints, and SysMLSim configurations must be created via the Enterprise Architect 13 Simulate ribbon.
According to SparxSystems, this integration with OpenModelica enables an equation based modeling of complex interacting engineered systems within the automotive, aerospace, robotics and power plant industries, e.g. systems containing mechanical, electrical, electronic, hydraulic, thermal, control, electric power or process-oriented sub-components. OpenModelica supports analysis of changing design and usage scenarios, and it speeds up development by evaluating and improving variants earlier in the design process.
The following screenshots illustrate the OpenModelica SysML simulation in Enterprise Architect 13.
