虚功和maxwell方法怎么算出的力不一样?
计算结果如下:我是初学者,高手指导下谢谢!SUMMARY OF FORCES BY VIRTUAL WORK
Load Step Number: 1.
Substep Number: 1.
Time: 0.1000E+01
Units of Force: ( N )
Component Force-Y
XIANQUAN-0.51738E+06

SUMMARY OF FORCES BY MAXWELL STRESS TENSOR
Units of Force:( N )
Component Force-Y
XIANQUAN-0.14640E+06
__________________________________
Note: Maxwell forces are in the Global Cartesian coordinate system.
Virtual work forces are in the element ESYS coordinate system.
The forces correspond to a full 360 degree revolution of the cross
section (an axisymmetric model).
The following element table items are available for printing and
plotting of the forces obtained by Virtual Work and the Maxwell Stress
Tensor methods.
Element Item Name Method Direction
FVW_Y Virtual Work Y
FMX_Y Maxwell Stress Y

剖分的问题还是时间、时间步长的问题?
