瞬态热传导问题的并行混合 EBE算法

A Mixed EBE Parallel Algorithm for Transient Heat Conduction Problems

结合有限元法，研究了 Ｅ Ｂ Ｅ 策略在热传导问题并行计算方面的应用，给出了瞬态热传导问题的并行混合 Ｅ Ｂ Ｅ 算法。根据所用 Ｃ Ｐ Ｕ 个数并行计算单元刚度矩阵，而总刚度矩阵 Ｋ 不需要组装，仅在“单元级“上进行各种计算。通过在并行计算机 Ｃｈａｌｌｅｎｇｅ 上的数值试验表明，算法是高效的。

With the finite\|element method, the paper studies the application of the EBE parallel algorithm in computing heat conduction, and a mixed EBE parallel algorithm for transient heat conduction is given. According to the number of CPU, the stiffness matrices are computed in parallel, but the total stiffness matrix needn't be formed. All of the computations are performed on the element level. The numerical experiment on Challenge computer shows that the algorithm is very effective.
