Software for Modeling and Simulation of Permafrost Processes
FSA-prognoz is a software for modeling and simulation of permafrost processes, custom developed for the company Fundamentstroyarkos. FSA-prognoz is our company’s first simulation software development for permafrost thermal stabilization. The FSA-prognoz numerical solver (developed in 2012) is based on ten years’ experience accumulated by our company in the numerical simulation of heat-and-mass transfer in the ground.
- The software constructs three-dimensional computational domains considering terrain and soil structure;
it takes into account:
- Unfrozen water content in the ground and water-ice phase transition;
- Convective heat transfer and constant water flow velocity in the soil;
- Influence of snow cover thickness;
- Operation of cooling devices – heat pipes, depth cooling units, Flat Loop & Hybrid Flat Loop TF;
- Influence of external thermal effects – sun or gas flare.
FSA-prognoz carried out long-term predictions of permafrost conditions at the bases of buildings and structures to reflect changes in a variety of factors, such as technological impact of climate change and environmental conditions.

FSA-prognoz: simulation results
The FSA-prognoz mathematical solver is based on the numerical solution of the heat equation using the finite element method and is implemented in C ++. FSA-prognoz is designed for 32-bit architecture and executes on one CPU’s core.
Developments on this scale normally take at least five years, so to significantly accelerate the FSA-prognoz development program, we used the patented software framework – Simmakers CAE Platform: an environment designed to create software systems to perform numerical modeling (simulation) of various physical and technological processes and the corresponding three-dimensional visualization.
