在边界条件螺栓预紧力显示界面，怎么能做到第二张图中的效果，我的（图1）会把所有螺栓预紧力单独显示，但是我看别人的可以合并，如图2，请问是施加方式的问题还是显示设置的问题？我是使用对象生成器批量生成的

Hi,

It seems in the first image separate bolt pretension objects are applied on the bolts. In the second image, multiple bolts are selected under a single bolt prestension object. Then the Random option has been used under Display to have different colors for the pretension objects.

First of all, thank you for your reply.

I use beam elements instead of bolts, when the "Scoping Method" is "Beam Connection", I can't select multiple bolts under a single bolt prestension object; they can only be applied one by one.(As shown in Figure 1)

When the "Scoping Method" is "Geometry Selection", the same problem occurs: it can only be selected one-to-one.

May I ask how I can achieve what you mentioned: "multiple bolts are selected under a single bolt prestension object".

THANKS!!!

In Ansys Mechanical, the ability to group multiple bolts under a single bolt pretension object depends on the type of elements and the scoping method used. For solid bolt geometry, you can select multiple bodies or faces and apply a single bolt pretension object. However, the software only allows you to assign one Beam Connection per Bolt Pretension object; multiple beam bolts cannot be grouped under a single pretension object using the "Beam Connection" scoping method.

Thank you for your reply, it feels like the problem is already half solved.
But when I select the four faces as the bolt preload application surface, it shows up yellow

I understand. Now I have created a coordinate system that can represent the axial directions of these four bolts and changed the selection from face to body, and the problem is solved.
