Abaqus6.5的一个新功能&合并已经分好网格的零件
Abaqus6.5的一个新功能合并已经分好网格的零件
在ABAQUS66.4的CAE中，碰见一个零件有很多重复特征的情况时，划分网格很困难。因为它不象ANSYS哪样可以复制划分了网格的PART,这个问题已经在6.5版本中得到解决。
比如说一块板子上面有很多个同样尺寸的圆柱，规则排列，这样你可以只建立一个小的PART,对这个PART划分网格，再再ASSEMBLY中重复生成这个PART
的INSTANCE, 再把这些INSTANCES
合并（MERGE）起来，合并后的大零件自动划分好了网格，这样大大减少时间。
以下是帮助文件中的解释：
Merging meshed part instances
Select InstanceMerge/Cut from the main menu bar to merge multiple
instances of meshed parts. Although merging meshed part instances
is similar to merging native part instances, you cannot cut
instances of meshed parts.
The meshed part instances can be:
&Orphan mesh part instances
&Meshed dependent part instances (where you have
already meshed the original part in the Mesh module).
&Meshed independent part instances (where you have
already meshed the part instance in the Mesh module).
&Any combination of these three.
You can merge multiple meshed part instances. Merging meshed part
instances is similar to merging unmeshed part instances in that the
operation creates a new part instance and a new part. Similarly,
you can choose to suppress or retain the original meshed part
instances. If you have already meshed parts that you created with
ABAQUS/CAE, you can choose between merging their geometry or
merging their meshes. If you choose to merge their geometry,
ABAQUS/CAE creates a new part instance and a new part and the
original meshes are deleted in the process. If you choose to merge
their meshes, ABAQUS/CAE creates a new orphan mesh part instance
and a new orphan mesh part and the original meshes are merged into
a single mesh. The discussion in the remainder of this section
assumes that you chose to merge the meshes of the selected
instances.

你可能喜欢abaqus 怎么分开显示两种材料的云图
两种材料?ABAQUS本身会显示所有以装配计算后的单元云图.你所说的应该是两种材料性能差别很大,某处材料材料应力很小,另一个材料应力很大,导致应力梯度划分集中显示在应力大的部件中,而小应力部件只显示一种颜色.这个可以自己设置应力梯度,例如原理梯度为0.1,50,100 ,200,300,400 ,500,你可以修改设置为0.1,0.15 ,0.18,0.2,100,200,500,这样就可显示出小应力部件的应力梯度.设置为contour options>basic>contour intervals>interval type>user-define>edit intervals,然后双击数值就可以修改了.
