CFDTwin: An open-source GUI and Python toolkit for POD-NN surrogate modeling of ANSYS Fluent simulations
arXiv:2605.27725v1 Announce Type: cross Abstract: High-fidelity computational fluid dynamics (CFD) is widely used for thermal-fluid design, but repeated CFD solves remain expensive for design optimization, uncertainty analysis, and digital-twin workflows. Recently, our team has demonstrated that a proper orthogonal decomposition and neural-network (POD-NN) surrogate can predict two-dimensional thermal fields in an electronics-cooling cold plate with large inference speedups while preserving physically interpretable modal structure. Reproducing and extending such workflows, however, typically r
The increasing computational demands of thermal-fluid design, coupled with advancements in AI and open-source tools, are driving the need for more efficient simulation methods.
This development allows for significantly faster and more accessible computational fluid dynamics (CFD) analysis, accelerating design optimization and establishing digital-twin capabilities across various engineering fields.
The barrier to entry for advanced CFD modeling is lowered, and the speed at which complex thermal and fluid interactions can be simulated and optimized is drastically improved.
