First off, I wanted to let you know that I am now driving the wheelchair model with actual patient force and moment push-rim data, and I wanted to thank you...
Hi AnyBody-People In the meantime my AnyBody-model is `walking' quite nicely (but perhaps still a bit groggily). My model consists now of one leg and the...
Hi Christine It sounds great that your model is walking I have answered your question below ... and ... be ... in ... muscles ... knee ... therefore ... these ...
Dear Group Members Those of you who have not yet seen the new gait model developed recently by the AnyBody Research Group might want to take a look at the ...
Hello! My name is Yoann and i'm working on a project for my master degree. I'm from the french Alps near Evian and i'm in Montreal for a while (studies). A...
Hi Yoann Welcome to the group I have tried to answer your questions below ... while ... I am not sure i understand what is it you would like to do. Normally we...
Dear Anybody support, I will try to precise the aim of my questions. ... insertation ... The first part will not necessary be in Anybody : I would like to ...

Hello hello! How do you proceed to calculate the moment arm in Anybody? If the muscle is "only" wrapped around the bony surface, in the case I described for...
Hi Yoann, Welcome to the group! If a muscle is wrapped around a cylidrical surface and the joint center is at the center of the cylinder, then the moment arm...
Hi, in my gait-model I want to calculate the joint contact forces and moments, especially the ones in the hip. Therefore, I used the AnyForceMomentMeasure and...
Hi Christine The AnyForceMomentMeasure measures in the global reference system by default. If you want to have the forces in the local coordinate of the hip...
The objective function is stated as a function of a zeroth order term, first order term (with an epsilon_1 coefficient), and second order term (with an...
Hi Sarah, I think you can find the answers you are looking for in the tutorial on inverse dynamic analysis: http://www.anybodytech.com/76.0.html. Please notice...
Dear support team I want to check the moment arms of some muscle: is there a way to calculate the instantaneous muscle moment arm? The muscle length change in...
Hi Christine Yes it is possible to measure the effective moment arm. This is done by setting the joint velocity to 1, if you then look at at the muscle...
Hi All, I have been working on putting together a single-upper-arm model, following step-by-step the online building block tutorial (except, of course, I was...
Hi Sarah The first warning that you get is not fatal if you get it at load time. It means that one of the points that the muscles passes through is located...
Hi, Thanks for getting back to me so quickly. Unfortunately though, I am still having a hard time with the model. Interestingly enough, when I close out...
Hi Sarah Sorry about your problems.. I think you should try to take it in two steps 1 make sure the kinematics of your model is running 2 solve the muscle...
Hi, I am facing little problems withSTL files in AnyBody. I a musinf STL files to represent the bony surfaces. I have attached muscles to these bones. These...
Hi Kiran The muscles can not wrap directly on an .stl or .anysruf file, this is why they penetrate through the bone. The .stl and .anysurf files are purely for...
Hi, Thanks for the suggestions. Actually the figure size is so large that it couldn't fit in the window. When i scaled the figure it worked fine. Regards, ...
Hi All, My name is Oskar, Im currently working in a motion analysis lab in point pleasant, NJ. We have been doing kinematic studies on a variety of topics. I...
Hello Oskar, and welcome to the group. Please feel free to ask questions here whenever you want. License prices and conditions: I understand that you are in...
Dear group members, There might be some members here who are unaware of the existence of the AnyBody Interest Group. It is a group of people who have signed up...
Hello, I've been trying to reproduce a 3-D sway study using AnyBody and have a little difficulty. The model I'm using is quite simplified for now in that the...
Hello Sunwok, Before going into a long exlanaion, I just want to be sue that you have read this tutorial: http://www.anybodytech.com/57.0.html If not, then it...
Hello, As you pointe out, the model was over-determined. After keeping DoFs and the number of constraints, the kinematic analysis was done without a relaxed...
