瞬态motion问题
现在有一个问题,在求解瞬态时,我设了一个旋转的motion,但band与固定部分的间隙较小时(0.5mm左右),分析时就会报错。报错内容如下,大家帮忙分析下Could not map vertices on the moving mesh band.Possible causes are: 1) Motion setup is not correct. 2) The model uses rotational motion, the geometry is less than a full circle, and master-slave boundaries were not defined on the surfaces of the wedge. 3) The model uses translational motion, and true surface curves were used on the band object or on the outermost faces of moving objects. 4) Extremely small gaps or faces exist in the geometry. These may need to be removed or enlarged.
