基于Trilinos程序包中的AztecOO和ML package开发了并行Poisson求解器。在非均匀的结构化网格上实现了复杂金属/电介质几何体的建模。 Poisson方程通过有限体积方法离散形成求解矩阵，然后利用Trilinos进行并行矩阵求解。并行测试表明，求解器的收敛表现良好，在典型情况下性能满足需求。这一求解器代码可以用于从等离子体模拟到传热过程等多种任务。%A Poisson Solver based on AztecOO and ML in Trilinos is developed. The metal and dielectric ob-ject with complex geometry is modeled in a non-uniform structure grid. Poisson equation is discretized by finite volume method to build a sparse matrix. The sparse matrix is solved paralleled with Trilinos. The benchmark show good convergence rates and satisfying performance. This solver code can be used for kinds of problem as plasma simulating and heat transfer.
