Fast Solution of the Heat Equation in Additively Manufactured Metals

本研究将探讨模拟粉床添加剂制造机体腔内换热的可行性。学生将研究不同可能的算法，并在CUDA中编写代码，以便在NVIDIA图形处理器上运行。结果将与实验测量结果进行比较。结果将是：哪种算法最合适？为什么？多大的体积可以实时或更快地以足够的精度(根据实验进行验证)进行模拟？用这种方法制造的零件的冶金性能能与产量相关联吗？

The research will be on investigating the feasibility of simulating the heat transfer inside the build volume of a powder bed additive manufacturing machine. The student will investigate different possible algorithms and code them in CUDA to run on an Nvidia gpu. The results will be compared with experimental measurements. The outputs will be: which algorithm is most appropriate and why? How large a volume can be simulated with sufficient accuracy (validated against experiment) in real time or faster? Can the outputs be correlated with metallurgical properties of parts built in this way?
