 January 24, 2009, 13:21 latest OF-1.5.x fixed the prob #1 Senior Member   Pei-Ying Hsieh Join Date: Mar 2009 Posts: 317 Rep Power: 9 latest OF-1.5.x fixed the problem when the domain rotating to 180 degree. I just ran a case where the domain moves from 0 degree to 180 degree, then, rotates back from 180 to 0 degree. As time reached 0 degree, solver crashed. If I changed from 0 degree to 0.0001 degree, then, run continues without problem. Pei

 January 24, 2009, 14:25 Could you post the motion desc #2 Senior Member   Join Date: Mar 2009 Posts: 854 Rep Power: 13 Could you post the motion description so we can reproduce the problem here? Thanks H

 January 25, 2009, 16:32 Hi, Henry, Below is the err #3 Senior Member   Pei-Ying Hsieh Join Date: Mar 2009 Posts: 317 Rep Power: 9 Hi, Henry, Below is the error message. I will see if I can post the motion profile.
