Accuracy Improvement Technique of DNN for Accelerating CFD Simulator

Understand

There is a Computational fluid dynamics (CFD) method of incorporating the DNN inference to reduce the computational cost.

• The reduction is realized by replacing some calculations by DNN inference.
• The cost reduction depends on the implementation method of the DNN and the accuracy of the DNN inference.
• Thus, we propose two techniques suitable to infer flow field on the CFD grid.
