不同单元类型的连接...........

84265369

请问各位，在I-DEAS里，不同类型单元共存在一个模型中，连接部位怎么处理啊？比如，梁单元与实体单元连接处，梁单元节点要怎么处理，才能传递力矩，解算时才能不出PIVOT 错啊？ 仿真分析,有限元,模拟,计算,力学,航空,航天,ANSYS,MSC,ABAQUS,ALGOR,Adina,COMSOL,FEMLAB,Matlab,Fluent/LQ!p

If you want to construct beam elements on surfaces of a meshed volume, you can do as follows:
1. Before the volume is meshed, create points on the surface exactly where you want to connect the beam elements.
, k' N9 ^( m- g: B8 N4 d, [2. Create anchor nodes on these points by clicking "Create anchor nodes" in the menu. Then press and hold MB3, select "Project from points". Click the destination points, then return.  Select the surface on which points are located as prompted. Then press enter, enter, .....Yes, till you see the anchor nodes appear on the screen.
. R4 u$ m8 Q& I% R3. Mesh the volume. There you can find nodes are coinciding on the anchor nodes or points.
4. Construct beam elements connecting these nodes.
