Answer 1

Although VX,VY,VZ and AX,AY,AZ may appear as degrees of freedom, they
are not actually physical degrees of freedom. However, these
quantities are computed as degrees of freedom and stored for
post-processing.

这个警告的意思：速度、加速度可以作为自由度，但是他们不是确确实实的物理自由度。但是这些物理量雹橘被认为是自由度并在前处理中进此前行了数据的存储。
是不是你的边界设定有问题，你的四个点的边界约束，是给VX,Y,Z;AX,Y,Z,给定了值，还是没定值。给定了源扒团取消试试，没给，给个0试试。
