Application deadline: 28th of March 2021


The GATE Institute is seeking to appoint Researchers in 3D City Modeling, Analysis and Simulation, who will be intricately involved in the GATE City Digital Twin project. It is a large interdisciplinary flagship project aims at developing a digital twin platform for designing, testing, applying and servicing the entire lifecycle of the built environment. This ambitious research project will be developed for the first time in Bulgaria. Crucial to its success is the building of semantically enriched 3D model of a city and the further development of the underlying scientific methods and technologies to facilitate the simulation and analysis of city scenarios (urban planning and design, infrastructure development, buildings’ energy performance, air and noise pollution, etc.). Specific semantics will be developed that address city-scale simulation requirements. This may include the development of new or contributions to emerging Application Domain Extensions for CityGML, meaningful integration of data from heterogeneous sources and semantically enrichment with additional data (e.g., social data), design and implementation of relational (i.e., PostGIS) or a graph database (i.e., Neo4j) to store and import/export geospatial data.

We are looking for junior and experienced researchers to build a multidisciplinary team that will go beyond to development of digital replicas and visualizations. The team with a diverse and flexible skillset should explore the full potential of integration of data from all stages of urban development and solving complex problems in urban modelling, simulation, analysis and visualization.


Junior researchers (R1) - Urban Simulations




• Involved in all phases of the CFD workflow, including geometry cleanup/defeaturing, structured-overset grid generation, application of CFD solvers;

• Construct CFD simulations at different levels-of-detail (to support CFD at different urban scales) and ensure that these can be directly used in an urban simulation software;

• Integrate CFD simulations in 3D city models;

• Scientific paper writing;

• Keep up-to-date with latest technology trends;

• Engage in appropriate training and development opportunities.


One or more of the following responsibilities:

• Link domain-specific simulation programs to each other to support rapid prototyping, integrated whole-system level analysis, and model-use during operations;

• Developing applications for visualization of CFD simulation data in augmented reality.


Skills, Experience and Qualifications


• А minimum of bachelor's or master's degree in computer science, applied mathematics, engineering, or in a related discipline;

• Experience working with scripting and programming using Python, Java, C++, Scala, R, or other;

• Strong skills in turbulence modelling, CFD mesh generation in complex 3D geometries;

• Strong prior experience in CFD;

• Experience with OpenFOAM, ANSYS, StarCCM, or other simulation tools;

• Solid oral/written communication and presentation skills in order to explain the outcome of research (and value thereof) to coworkers and peers;

• Ability to prioritize tasks and work on multiple assignments, and a deep desire to find ways to create value and deliver results.
