This is a error created in the FEM engine which warns of dangerous distortion in the mesh of a 3D simulation. The two main causes for this error is a negative jacobian shape which cannot be resolved or a lack of flow stress values. In the case of the negative jacobian, the problematic elements (along with the node coordinates for the problem elements) will be listed in the file BUG.MSG. If every element in the mesh is listed, the flow stress for the object was probably not defined. If there are only a few elements listed, the user may try to load the bad step into the Pre-Processor and check the shape of the elements and the Boundary Condition code. The importance of well defined boundary conditions can not be overemphasized. This includes meaningful contact conditions and fixed velocity conditions.

差劲的元素形状
这是在 3D立体模拟的网孔中警告危险扭曲的 FEM 引擎中产生了的一个错误。 对于这一个错误的二主要的因素是不能够被决定的否定的 jacobian 形状或缺乏流程压迫力价值。 在否定的 jacobian 的情况，棘手的元素 (连同节坐标一起对于问题元素) 将会在文件 BUG.MSG 被列出。 如果在网孔的每种元素被列出, 对于物体的流程压迫力是或许不定义。如果只有被列出的一些元素,使用者可能试着装载差劲的步骤进入前处理器而且检查元素的形状和边界情况密码。 定义良好边界情况的重要不能被过份强调。 这包括意义深长的连络情况和固定的速度情况。
