First,thanks for your replay. I have checked the gound force applying calcns following your suggestions but no gain anything following pictures are results and I need your deep help. https://m.qpic.cn/psb?/V12VR5pc48gAdz/Wag2bgtuZuVYnQl*k6mjwl0XcpUZoDeK37PNJRomf.8!/b/dCEBAAAAAAAA&bo=FAaAAgAAAAADB7I!...

hi,
everyone
I have two problems need your help
1. why the value of FY is so high at the beginning of caculation?(PS. the seem situation appeared ID results)
2. why ligament forces which plot from force file are so strange after OS ?

Thank you for your reply!

hi,
everyone
Why is the model moving down first and then moving up in RRA?
I have checked the troubleshooting but no result, so I need your help.

hi, I'm recentently building a model using personalized bone geometry by nmsbuilder which can generate a .osim file including mass,intertial, etc. When I understood the COM on OpenSim, I confused that .VTP files are Solid or hollow which have great impact on segment COM. I have known that opensim so...

hello everyone,
I have got static optimization results and wanted to compare with the experimental results, but the time of test and simulation inconsistent, how can I solve this problems？
thanks.

First thanks for your replay
I have drawn the ground force and it is similar,so I thought input data is no problem，Noteworthy thing is that second right foot corresponding force is more reliable compared with other literatures.
thank again.

Hello everyone,
there is a problem need your help
I would like to know about the result of JointReaction forces why force is similar while the results differ greatly,as following attachment which the locations of mark R .
thank you.

hello， I have some problems about results and need your help 1. nine components fx,fy,fz, mx,my,mz, px,py,pz given when I use analyze tool , but I do not know how to calculate the joint force use this components，just f？ 2.Because there is a contact in my model and it can not perform static optimizat...
