Seamlessly couple CFD, FEA, and 1D tools to automate complex thermal workflows and achieve unparalleled simulation accuracy.
Power Efficient Co-Simulation with Intelligent Automation
CoTherm is an advanced process automation and CAE coupling software designed to streamline the most complex multi-physics simulation workflows. It serves as the intelligent bridge between disparate simulation tools, allowing engineers to synchronize simulations of 3D high-fidelity thermal models, CFD models, 1D system models, and other analyses. By automating data exchange and iteration, CoTherm eliminates the manual errors and time-sinks traditionally associated with co-simulation.
The software is engineered to maximize engineering efficiency through a visual, task-based process workflow. It enables the creation of sophisticated simulation pipelines – including automated meshing, solver execution, and post-processing – without requiring extensive custom coding. With CoTherm, organizations can achieve automated high-fidelity co-simulation workflows, ensuring that every simulation technique is accounted for across the entire design cycle.

Design of Experiments (DOE) & Optimization
Engineering is rarely about a single simulation; it’s about finding the best design within a set of constraints. CoTherm automates the “what-if” process by driving solvers through hundreds of iterations to identify sensitivities and optimal configurations. This capability moves the engineer from being a “tool operator” to a “data analyst,” as the software handles the tedious task of launching, monitoring, and harvesting data from design sweeps.
