Incomplete selection for periodic condition
Webcally combining modified incomplete Cholesky (MIC) factorizations[12] and Sherman-Morrison-Woodbury (SMW) update[9]. Theoretical analyses show that with these new preconditioners, the condition numbers of the preconditioned matrices can be reduced to O(h−1), one order smaller than the condition number O(h−2) of the original matrix A. The ... WebJul 27, 2024 · 1. If the flow is indeed symmetrical, then you should be able to use the symmetry BC. You should be able to continue using the symmetry condition. 2. In this case, the flow is not going to be symmetrical. You will need to model the entire geometry and cannot use a partial domain. Thanks.
