Prediction of melt pool flow in metal additive manufacturing
by parallel computing with multiple GPUs
In laser powder bed fusion, melting, flow and solidification proceed simultaneously on micrometre and microsecond scales. I build models that resolve these coupled phenomena and run them at high resolution using multi-GPU parallel computing and adaptive mesh refinement.
