在 " Analysis Setting" 里面有一个 “output control" 的选项,看一下你是不是有些选项是不是 ”NO“。
我猜测应该是你的 "Node Force" 开关没有打开。 如果这个还不行,看看还有那些开关没打开的,打开看看能不能解决问题。
PS:楼主是要看接触力? Force reaction 在用在接触上的时候,如果反力结果不合理,有些地方要注意,帮助文档如下:
Contact Based Force Reactions:
For a force reaction scoped to a contact region, if you set Extraction = Source(Contact Element), the reaction calculations come directly from the contact elements themselves. This results in accurate force reactions even when the contact region overlaps with other boundary conditions, such as other contact regions, supports, etc. Characteristics of the Source(Contact Element) setting are that MPC contact is not supported, nor are reactions from the Target(Underlying Element) side. This feature should only be used with Asymmetric contact and requires that Calculate Miscellaneous be set to Yes in the Output Controls.
A limitation of the Source(Contact Element) setting is when you use linear contact (that is, either Bonded or No Separation contact types) with loads that are unrealistically very high or very low in magnitude. These situations can produce inaccurate force reactions.
