Hi again and thanks for you're help. I implemented my matrix using youre template however I got an intresting error.

As I understands it, this is due to the 

 

Matrix(r, c, init, ro, sym, sc, sh, st, o, dt, f, a)

 

function that the simulink matrix is made for but why it is not working is another question. Do any wise person out there know posibly why?

Thanks again for all help

Hi

I think it is an algebraic loop as well, it is proberbly connected to two sperical joints that are supporting a prismatic joint. This was my way of trying to emulate a spring but is clerly wrong. 

So I need to find a spring component that is capable of moving in 3 directions. (being fixed to ground in one side and the other side conedcted to a 6 dof robot end effector) Any sugestions?

 

Thanks for your help

PS trying to upload the model, a bit new to maplesim.
