内存和网格数量的关系?
-
@搬运工不好当 之前估计过,在我计算里面是大约100万网格占4G内存,具体和方程数量以及模型有关。
最新的fluent 中提到,直接可以在mesh -> info->memory usage 中查看。
也就是大约32g 电脑算800万网格就不容易了。
ANSYS Fluent has a feature that will report the following information: the numbers of nodes, faces, cells, edges, and object pointers (generic pointers for various mesh and graphics utilities) that are used and allocated; the amount of array memory (scratch memory used for surfaces) used and allocated; and the amount of memory used by the solver process. -
@taiwangwsg 对的,从湍流模型上面RSM 计算需要的内存也远远高于k-e模型
