Original abstract
The paper presents our developed GPU-based heat transfer and solidification model for continuous casting, which is coupled with a submodel used for the prediction of the steel micro-structure. The model is implemented in CUDA/C++, which allows for rapid computing on NVIDIA GPUs. The time-dependent temperature distribution calculated by the thermal model is iteratively passed to the submodel for the steel micro-structure prediction. The structural submodel determines the spatially-dependent rates of temperature change in the strand, for which the interdendritic solidification model IDS predicts the micro-structure of steel.

Článek prezentuje vyvinutý GPU model přenosu tepla a tuhnutí pro kontinuální lití, který je spojen se submodelem pro predikci mikrostruktury odlévané oceli. Model je implementován v CUDA / C ++, což umožňuje rychlé provádění simulací na GPU NVIDIA. Rozložení teploty v čase vypočítané tepelným modelem je předáváno do submodelu pro predikci ocelové mikrostruktury. Strukturální submodel určuje prostorově závislé gradienty teploty, podle kterých následně predikuje mikrostrukturu oceli s využitím modelu interdendritické solidifikace IDS.
