MD Adams刚柔接触应力显示问题

请教各位版主以及高手
再用MD Adams计算刚柔接触问题时，开始用Fortran的求解器，计算报错
WARNING: Model .model_1 is no longer compatible with Adams/Solver (FORTRAN).
.model_1.CONTACT_6 may be causing the incompatibility because of one or more
of the following:
- Objects of type Contact are not compatible with Adams/Solver (FORTRAN).
- The topology of the model has changed so .model_1.CONTACT_6
is no longer connected in a way that is compatible with
Adams/Solver (FORTRAN).
- An attribute of .model_1.CONTACT_6 is no longer compatible with
Adams/Solver (FORTRAN).
这个CONTACT_6 就是刚柔接触，所以就把求解器改成了C++
就可以计算了，但是在后处理中，无法显示柔体的各种应力分布情况（柔体用Nastran得到的mnf文件，各种应力也选了）
报错
WARNING: There is no Von Mises Stress information for any of the bodies in the default view.
The contour plot legend visibility has been turned off.
前面看过一个帖子，说可以选择Tool/Plugin Manager/ Durability/von Mises
但是还是无法显示，弄了几天也没什么结果
各位版主以及高手帮忙救命啊
