deltatheta aims to revolutionise modelling and simulation in engineering, and bring model-based engineering firmly into the design process. Our software tools are "designed for engineers by engineers" with user interface and integration into tools and processes taking priority. every engineering industry is driven by energy efficiency to achieve goals in cost, performance and environmental impact. only with system simulation can the control, operation and efficiency of integrated systems be understood.Products:- Vertex: Modelica based modelling and simulation tool- Converge: Model lifecycle management and version control tool for Modelica models- Modelica SDK: for integration of Modelica into software and processesServices: Simulation strategy, model development, engineering consulting
