Following is an example LEDG input file with 6 constraints:
-------------- begin included file --------------
dimensions 2 2 2 constrain x0 constrain x1 constrain y0 constrain y1 constrain z0 constrain z1 body 1 0 0 0 1 0 0 0 1 0 body 2 0 0 1 1 0 1 0 1 1 body 3 1 1 0 1 1 1 end
-------------- end included file --------------
And below is the evolver data file produced by it:
