最近植入了一个高阶格式,但是偶尔收敛,偶尔发散。简单流场收敛,复杂流场发散。卡住了2个星期。今天回头再去看原始文献,发现后面一句话。
improved solutions for problems where the velocity field is constant or slowly varying over a range of cells
slowly varying over a range of cells
写的还是很严谨的。估计原作者测试过复杂流场,还是不收敛..一生和收敛抗战。
并行计算对收敛有没有影响?
? 目前我的计算最多5000网格,秒算,还不需要并行 :big_mouth:
@李东岳 李老师,请问发散后继续计算又不发散了,比如如下报错: 或者报错与solver有关(gauss-seidel),这证明植入的模型还是不容易收敛是吧?
