I have looked through the lastest version i have of the model. In
the JointsAndDriver.any file there is an issue that could cause the
In the SeatHeight driver the Reaction.Type is set to zero’s meaning
that this driver do not provide any force. They should all be one
unless you have something else to support the pelvis?
The next thing i would check is the environment ie. the wheelchair,
it should be checked that the reation.type settings on the chairs
are the same on all drivers.
In the Environment.any file i can see that in my version there is no
forces acting between the rims and the hands, since this part has
been outcommented. Naturally this needs to be swithed in again,
otherwise there is no forces acting there.
I hope some of it can be used…
