Assignment 8-Run Times

Please list here your simEngine3D run times. Use this format:
Simple pendulum: blah milliseconds
Double pendulum: blah blah milliseconds

Thank you,
Dan

Re: Assignment 8-Run Times

Single Pendulm - BDF order 2 - Time Step = 0.005s
8.739711 seconds

Double Pendulm - BDF order 1 - Time Step = 0.005s
(Revolute to ground & spherical joint between the Pendulums)
13.988516 seconds

Double Pendulm - BDF order 1 - Time Step = 0.005s
(Two Revolute joints)
16.038917 seconds

Re: Assignment 8-Run Times

Simple pendulum: time step = 0.01
41.98 seconds

Double pendulum: time step = 0.01
73.29 seconds

Using Object-oriented methods seems to take longer to compute.

Re: Assignment 8-Run Times

Simple pendulum:
h = 0.01 s
Simulation time = 28.87 s

Double pendulum:
h = 0.01 s
Simulation time = 49.22 s

Re: Assignment 8-Run Times

Simple Pendulum:
h = 0.01 s
T = 109.4 s

Double Pendulum:
h = 1e-4 s
T= 603.59 s

I guess I over-killed the double pendulum time step a little. I'm not sure why the simple pendulum takes so much longer than everyone else's. It may just be that I didn't focus on coding for speed.

Re: Assignment 8-Run Times

Simple Pendulum:
stepsize = 0.01s
10 seconds
BDF1 = 20.75s
BDF2 = 24.60s

Double Pendulum:
BDF1 = 56.14s
BDF2 = 67.02s

Re: Assignment 8-Run Times

Single Pendulumn
BDF2
h = 10^-2
time = 39s

Double Pendulumn (solution blowing up)
BDF2
h = 10^-2
time = 67s

Re: Assignment 8-Run Times

Fixed it!

Single Pendulumn
BDF2
h = 10^-2
time = 39s

Double Pendulumn
BDF2
h = 10^-2
time = 46s

Re: Assignment 8-Run Times

Single Pendulum:
dt = 0.01
BDF 2
runtime: 21sec

Double Pendulum
dt = 0.01
BDF 2
runtime 49.7sec
