The Institute of Numerical Modelling offers consulting services in mathematics, physics, civil engineering,  high-performance computing and numerical modelling. We have 20+ years of experience in developing diverse numerical models and analysing the resulting data. We tailor solutions to the specific needs of a client in terms of optimising manufacturing systems and processes. For instance, we can identify methods for improving the energy efficiency of buildings, among other areas of expertise.

The Institute of Numerical Modelling is a part of the University of Latvia. Our staff is highly qualified (mostly with a PhD or a Master’s degree) and are assisted by energetic science and engineering students. The staff of the Institute of Numerical modelling represents many different fields of science – physics, mathematics, computer sciences, geography, engineering, etc.

Flood Risk Assessment

We offer flood risk assessment for both private and state entities and evaluate areas or building sites specified by the client. We also assess the influence of climate change on the risk of flooding. We use climate data and MIKE suite for developing flood risk recommendations. We have developed the hydrodynamic models of the Daugava and Lielupe river basins.

Climate Change Influence Assessment

We perform a variety of climate data analysis, we evaluate the influence of climate change on transport, power industry, medicine, agriculture sector, etc. Using temperature, precipitation, wind velocity, cloudiness, and relative humidity data, we have developed tools to understand how climate change will influence wind energy, the number of sunny days, phenology, road conditions, visibility, migraines, and the risk of fire hazards.

High-Performance Computing (HPC)

We offer a full high-performance computing (HPC) solution cycle – we select or develop suitable software for each client’s specific needs, we modify it for HPC use, and we supply tools for data visualisation, input, output, and management.

We use self-developed, open-source, and commercial software (e.g. OpenFOAM, Elmer, COMSOL, ANSYS, R Statistics, Python, etc.) run on a 256 core HPC cluster. To supplement our array of HPC service solutions, we have an ongoing partnership with the High-Performance Computing Centre at the Riga Technical University. We also adapt the solutions for use in cloud-based services such as Microsoft Azure, Digital Ocean, AWS, Google Cloud Platform, etc.
