Key competences of ThetaFrame Solutions

Model development

Fast, project specific model development with open or closed source code.


Simulate complex systems with physics based-, statistical- or AI methods.

Detailed Result Analysis

Analyse and visualize simulation results, including thorough uncertainty estimates.


Summarize findings and methods in concise reports to be published or integrated in peer-review articles.

ThetaFrame knows simulations.

Simulations of phase change driven by thermodynamics in complex, turbulent flows demands a high level of detail. As an example, melting of an ice tube is driven by warm water flowing through the tube at high speed. By resolving the flow boundary layer as well as the thermodynamic boundary layer, it becomes possible to predict local heat transfer into the ice wall. This local heat flux drives phase change at the water/ice boundary which leads to a geometric change of the ice tube.
