Hi everybody,
i tried to run a case with cyclicAMI and non planar rotational patches (rotationAngle set). The case runs fine on a single or on a small number of processors. Using more processors results in cyclicAMI failing to initialize. After some observation I think that this error occurs when a processor holds faces from one ami patch but not from the other one. Please find a test case attached (pipe flow and a rotation angle of 60 deg). The case runs fine on a single processor and crashes in parallel. To reproduce run Allrun script. When the decomposition changed to force faces of both AMI patches on each processor it will run fine in parallel; change decomposeParDict to: Code:
simpleCoeffs { n (1 1 2); // n (2 1 1); delta 0.1; } Code:
