PREP0005221 Modelica Modeling Researcher
Digital Twin Modeling Researcher
Project Description:
Modelica Modeling in Support of a Building Digital Twin. NIST has several projects related to digital twins in the built environment. These projects are developing the infrastructure needed to ease the development and deployment of digital twins and inform existing and future standards. The Intelligent Building Agents Laboratory (IBAL) is being used in these efforts. A Modelica model was developed for the IBAL, but this model needs to be improved and updated so that it can be used to demonstrate the full physical-digital twin workflow. Guideline 36 controllers need to be added to the model, and the parameters that will be tuned to align the digital twin with the physical twin need to be identified. Some of these parameters are not tunable when the model is converted to an FMU for co-simulation, so some models will need to be modified or developed to make those parameters available after the FMU has been compiled.
Key Responsibilities:
- Review and understand the existing models
- Identify the parameters that need to be tuned
- Modify and develop new models as needed
- Add Guideline 36 controllers to the model
- Present results at internal meetings and occasional meetings with external stakeholders
- Ensure that results, protocols, software, and documentation have been archived or otherwise transmitted to the larger organization
Desired Qualifications:
- U.S. Citizen Preferred
- Undergraduate degree in Computer Science or Engineering
- Experience with Modelica modeling using the Buildings library
- Preferred experience with Modelica modeling in OpenModelica
- Preferred experience with FMUs and co-simulation in Python
- Strong oral and written communication skills
Other Details:
- Part-time: the participant is expected to work 20 hours a week
- Location: the participant will work remotely.
- Duration: this is expected to be a nine-month position. Extensions are sometimes granted depending on the availability of funds.
