 Author Comment/Response jkarges 12/29/11 7:30pm Hi, I'm working on a project where I need to plot the trajectory of the center of a rolling disk. I've solved for the necessary InterpolatingFunctions of the 5 generalized coordinates using NDSolve, and these plot nicely using the Plot[] function, but when I try to combine the x,y, and z coordinates in a ParametricPlot3D, the plot turns up blank. Here's a sample of my code: nhsol = NDSolve[ Join[{nhEOM1 == 0, nhEOM2 == 0, nhEOM3 == 0, D[C1[[1]].{q1'[t], q2'[t], q3'[t], q4'[t], q5'[t]}, t] == 0, D[C1[[2]].{q1'[t], q2'[t], q3'[t], q4'[t], q5'[t]}, t] == 0}, inits1] /. params, {q1[t], q2[t], q3[t], q4[t], q5[t]}, {t, 3}] (*Working singular dimension plots:*) Plot[(-aPc[[1]] /. params) /. nhsol, {t, 0, 3}] Plot[(aPc[[2]] /. params) /. nhsol, {t, 0, 3}] Plot[(aPc[[3]] /. params) /. nhsol, {t, 0, 3}] (*Non-working Parametric Plot:*) ParametricPlot3D[{(-aPc[[1]] /. params) /. nhsol, (aPc[[2]] /. params) /. nhsol, (aPc[[3]] /. params) /. nhsol}, {t, 0, 3}] Attachment: Project3.nb, URL: ,
