Plug-in-gait lower model for Jumping

kinematics
#1

hello,

When I used my own jumping C3D file in Plug-in-gait_Simple lower model , at the point of about 70% of inverse Dynamics, there is a error:

ERROR(OBJ.MCH.MUS4) : C:/U…s/pc/D…p/A…o/T…s/A…p/AnyMoCapModel.any(59) : InverseDynamicStudy.InverseDynamics : Muscle recruitment solver : solver aborted due to singular KKT matrix

What should I do with it?

Thank you.

@Nickel_Lee Are you using ground reaction force prediction in your model? Or is this with measured forces from a force plate?

#3

hello

With the measured forces, I’ve already solved it. Since the new AMMR2.2 have been released, I’ll try to use the newest models to simulate and see what happens?

thank you.

楼主你好,我的plug in gait 的c3d文件导入anybody失败了,请问下该怎么导入啊?:slightly_smiling_face:感谢楼主不吝赐教啊

你好
双击打开Setup/TrialSpecificData_LowerExtremity.any
更改名字 TrialFileName = “zhangshiyu_Cal_11” to TrialFileName = “xxxxxxxxxxxxxxx”;
记得将C3D文件放入Input文件夹内
