ERROR
Step "Subcase - Contact Loads 1" has loads applied without any constraints.
操作：在“编辑解算方案”对话框中为此步骤定义约束或请求惯性释放。

ERROR
Step "Subcase -Max Compression Pressure  1" has loads applied without any constraints.
操作：在“编辑解算方案”对话框中为此步骤定义约束或请求惯性释放。

ERROR
Step "Subcase -Max Tensile Force 1" has loads applied without any constraints.
操作：在“编辑解算方案”对话框中为此步骤定义约束或请求惯性释放。

迭代求解器选项
More than 80 percent of the elements in this model are 3D elements.
It is therefore recommended that you turn ON the Element Iterative Solver in the "Edit
Solution" dialog.
