Hi all I am Madu from NY, USA doing my Master's in Mechanical Engineering. I have started working with AnyBody recently and I am going through the repository ...
Hi Manu, Damping is a reactive and dissipative force that is proportional to velocity. Forces in AnyScript can be specified as mathematical expressions, and...
Hi Atlas Yes the AnySphericalJoint is a so called ball and socket joint. So yes I think you do need an extra node to constrin the rotational degree of freedom....
Dear colleagues: I got my "joint-driven" model run. The problem has been resolved. The model works by using the joint positions extracted from "Interface"...
Hi William First of all welcome to the group. I am not sure I understand what you followed? If you wanna make an arm movement I thing you will need more than...
I added another node right in the middle and .1 off the z axis and added a driver for its postion, now I have 2 extra constraints for some reason, if anyone...
Is it common to make models follow motion data of specific points? To me it seems a rather large amount of error is introduced, because of the marker...
To all members: As a curtesy to readers please identify yourselves when asking a question. ... Yes it is a very common to impose measured movements on a model....
Hi Søren, I still have some problems with my shoulder-model. When I run a 45° abduction (I drive only the abductin in the gh-joint, the other values are ...
Dear Subscribers, We have just completed a new tutorial that explains some of the intricacies of driving models kinematically by means of motion capture marker...
Hello, Is it better to use a joint, or a driver with a measure in the model environment connection? Or does either method accomplish the same thing? In the...
Hello Brent, Joints and kinematic measures with drivers are both just constraints on the model, so if they express the same thing, then there is no difference....
Hi Alexander Sorry about the delay.. The error you get is a muscle wrapping error on the pectoralis_major_thoracic_part_5 muscle, so it will have an effetct if...
Hello folks, In the Anybody model, there are a total of 12 deltoid "parts" -- 6 that are scapular and 6 that are clavicular, in origin. Is there a way to...
John, I suspected that would be the answer (and now I remember you mentioning the knee joint example at the seminar). I am, in fact, assigning a distance to a...
Hi Atlas I have looked at your model and it is not preferable to drive your joint with two AnyKinLinear en global coordinates. If you change the one in the...
Hi Venn You are right about the anterio deltoid, The muscle named "deltoideus_scapular_part_1" is the most posterior of the deltoid muslce branches. So i think...
Hello, I am having trouble visualizing the direction of an applied AnyForce to a joint. Is there any way to have a vector drawn automatically? I know you can...
Hi Søren, I´ve still some more questions... The rotational matrix "Axes" of the gh-node of the humerus is calculated at every step of the simulation, so that...
Sure. Please refer to the section entitled "Variables and expressions" in the reference manual. Most algebraic functions you can think of are available. Best...
Hi Brent If you have two segments with an anykinlinear in between, and you apply a positve anyforce to the measure it will add a force acting in the positive...
Hi Alex Yes this is correct, the Axes property measure the orientation wrt to global for each time step. I am unsure about the rotations since i am not...
Hi Søren, It´s me again. I checked out your suggestion with the AnyVec3 to control my rotation of the forcevector. I inserted this control-function at the...
Hello Søren, The pedal demo I was referring to starts in Lesson 5 of the Building Block Tutorial. http://www.anybodytech.com/559.0.html In that tutorial, the...
Hello all, I am wondering what are the Contraints.Reaction.Fout values. As I run my model with and without muscles, I get different values for those....
I am still having trouble figuring out the directions. I have uploaded a copy of my model in AnyForce_Direction.zip I started with the standing model, and...
Hello Jean-Olivier, Contraints.Reaction.Fout is a menber of any constraint. It is the force(s) in the constraint. If the constraint is a joint then ...
