GrainGNN: A dynamic graph neural network for predicting 3D grain microstructure
Yigong Qin, Stephen DeWitt, Balasubramaniam Radhakrishnan +1
We propose GrainGNN, a surrogate model for the evolution of polycrystalline grain structure under rapid solidification conditions in metal additive manufacturing. High fidelity sim…
