Hi James, We are falling a bit behind with answering the questions here. Your approach looks ok, but the contact element you have defined (I prefer to call it...
Hi BC, This is a hard question to answer, and the blame is on me, I am afraid. I am lacking behind on writing a paper about the muscle model. Unfortunately it...
Hi Soren, We send you a simulation because we have the same error in a lot of test, the kinematic simulation is correct but when we make the dinamic analysis...

Hi Raul I have tried to test your model a bit. My conclusion is that it is mainly fluctuations in the accelerations whcih could be the root of your recruitment...
Hi Christian, I've ammended the initial positions that you have suggested but it's still the same scaling problem. After scaling, the model runs kinematically...
Hi Robin I can't load the model because you use a AnySailor.any? I don't have that one? I can change it to another one, but I don't know how yours are? Best...
Hi Robin I get some big kinematic errors. By looking at the loaded model, it seems like the model is not big enough... The legs are not long enough and they...
Hi, Your interpretation sounds correct to me. Thank for the idea. I'll try it out. Best Regards, Robin ... enough ... attached ... that ... case. I ... like, ...
Hi I have been trying to create conditional strength muscle to model ground reaction forces as follows: //measure position of right foot heel AnyKinLinear...
Hello Christian, Sorry for taking this long to answer. I uploaded a file called LIO.rar to the file section of the group. It contains the model and should be...
I am simulating a bicep curl with internal rotation, and while I can individually drive the elbow joint velocity (89.129 deg/s) and individually drive the...
Hello everybody, I am trying to create a model that stands on one leg only. First off, I just removed the lines, from the regular StandingModel where the left ...
Hi James, I believe you guessed right. I am sorry that the help is not very clear on this issue. During an operation, expressions are evaluated at different...
Hi Sebastian Here is initially a short description of the drivers of the standing model, it is driven in the following way: For both the right and left legs: ...
I have uploaded two files to the files section of the group - Validation I - cst arm angles, and Validation II - driven by Vicon. I am having problems with...
Hi Jean-Olivier Thank you, I am looking on your model and you will have an answer soon.... Best regards Christian, AnyBody Support ... LIO.rar to ... extracted...
Hi Soren, When we make the simulations, we obtain a list of photographs but the colors of the muscles are sometimes strange because the muscles became violet. ...

Hi Michael Many thanks for your reply. Did you mean an implementation as follows? //meaure position of right foot heel AnyKinLinear RightHeelPosition={ ...
Hello Søren, thanks for your fast reply! Just to repeat: I removed the constraint that fixes the left toe (1DOF) and the left heel (1DOF) as well as the...
Hi James, This sounds more tricky:-( Basically this error means that AnyBody cannot solve the equations of motion during the inverse dynamic analysis. There...
Hi Sebastian I have looked at my skecth of your model again, and i can not see what should be wrong It is correct that you remove three drivers on the left...
Hi Soren, Thank you for your quick answer, excuse me but I have another question about the photographs that we send you yesterday. We have a problem, when we...
Hi Raul I have looked at the pictures and it looks like the model is overloaded at certain parts of the analysis? and there are also fluctuations in the...
Hello Sarah, I apologize for the belated reply. ... You are quite right - I also get that error. However, when I use your model together with the next version...
