HI,
considering these values of angles for the heel and for the ankle:

AnyKinEqInterPolDriver RHeelGroundConstraint ={
AnyKinLinear HeelPos = {
AnyFixedRefFrame &Ground =
Main.Model.EnvironmentModel.GlobalRef;
AnyRefNode &Ball =
Main.Model.HumanModel.Right.Leg.Seg.Foot.HeelJoint;
};
MeasureOrganizer = {1}; // Only the y coordinate
AnyVector Time1 = { 0, 0.1, 0.2, 0.3, 0.4, 0.5, 0.56, 0.62,
0.67, 0.72, 0.77, 0.82, 0.95, 0.98, 1.0, 1.1, 1.17 };

T = .Time1;
Type = Bspline;
Data = {
{0, 0, 0,0, 0, 0, 0, 0, 0, 0.005, 0.01,
0.01,0.01,0.01,0.01,0.01, 0.01}
};

Reaction.Type = {1}; // Provide ground reaction forces
};

AnyKinEqInterPolDriver LHeelGroundConstraint ={
AnyKinLinear HeelPos = {
AnyFixedRefFrame &Ground =
Main.Model.EnvironmentModel.GlobalRef;
AnyRefNode &Ball =
Main.Model.HumanModel.Left.Leg.Seg.Foot.HeelJoint;
};
MeasureOrganizer = {1}; // Only the y coordinate
AnyVector Time1 = { 0, 0.1, 0.2, 0.3, 0.4, 0.5, 0.56, 0.62,
0.67, 0.72, 0.77, 0.82, 0.95, 0.98, 1.0, 1.1, 1.17
};

T = .Time1;
Type = Bspline;

Data = {
{0.0, 0, 0,0, 0, 0, 0, 0, 0, 0.005, 0.01,
0.01,0.01,0.01,0.01,0.01, 0.01}
};

Reaction.Type = {1}; // Provide ground reaction forces
};

and

AnyFolder LAnkleDriver= {
//AnyKinEqSimpleDriver LAnkleDrv = {
AnyVector Time = { 0, 0.1, 0.2, 0.3, 0.4, 0.5, 0.56, 0.62, 0.67,
0.72, 0.77, 0.82, 0.95, 0.98, 1.0, 1.1, 1.17 };
AnyKinEqInterPolDriver AnkleJointDriver = {

AnyJoint &ref1 = Main.Model.HumanModel.Left.Leg.Jnt.Ankle;
AnyJoint &ref2 = Main.Model.HumanModel.Right.Leg.Jnt.Ankle;
MeasureOrganizer={0,2};

//AnyRevoluteJoint &AnkleJoint =
Main.Model.HumanModel.Left.Leg.Jnt.Ankle;

T = .Time;
Type = Bspline;
Data = {{140,
136,
132,
128,
124,
120,
130,
140,
135,
130,
125,
120,
122,
125,
135,
140,
150

     },
     {  140,
         136,
    132,

128,
124,
120,
130,
140,
135,
130,
125,
120,
122,
125,
135,
140,
150

    } } * pi/180 ;

   Reaction.Type = {0.0,0};

   };// chiude AnyKinEqInterPolDriver

  }; // chiude il folder

I get an error :

Study : Kinematic analysis failed in time step 0.

Why?

are that values of angles of ankles and heels inconsequential?
how can I make up for?
I would like the heels to be lifted only in the instants related to
the times:
9,10,11,12, that is in the times:
0.67, 0.72, 0.77, 0.82,
how can I make?

I have need to conclude my model therefore I need your help!

Thanks so much
Raffaella

already gives me error to the beginning:

Hi Raffaella

It is difficult to tell exactly why you get this message, since i do
not have the overview of your drivers, there could be many reasons.

I could be that you have too many drivers on the model or that the
initial positions are too far away from the position that the model
shoudl end up in.

Some times it is a good idea to save the model when it is running
and then do small changes and check that these are running before
proceeding.

The sketched i would like to have should not be from AnyBody it
could be a handdrawing of a stickfigure showing the following

1 a skecth showing which possible reactions the model should have
with the ground and the bar, shown as arrows for each of the force
directions and angular arrows for each of the moments which should
be available.

2 a sketch showing the drivers on the model please, indicate for
each joint how it is driven.

You may upload the sketches in the File section of this group.

The values i gave for the heel motion where just arbitarily choosen
you may adjust them. Please be aware that for each value in the time
vector theres is a corresponding data value. So finding the data
value for the time=0.82 you will have to adjust nr. 12 of the data
vector if i counted correctly.

Best regards
