Thanks Dave, it is good to get some more sources to check my more obscure units but as far as I can tell what I am using is consistent. I will figure it out at some point.

I have a fairly simple model that when I run a steady state version provides results that are similar to what we see in the real world. However if I try to simulate the heat up process with a transient model it fails to correlate by orders of magnitude. I expect some variation given the...

Reference points are a nice way to pull deflection if you are just looking for a few points (with an mpc or coupling) L

The unit system is standard here anyway and make perfect sense for structural analysis. Your forces are in Newtons and stresses are in MPa with mm dimensions. Far more logical than any other way to skin that cat. The density is a bit strange but that is just a material property and not...

In the plastic filament type printers makergear M2 and ultemaker 2+ are a level above makerbot but the differences are not huge. For the money if the parts are machinable a CNC mill would give much better strength, speed and accuraccurace. There is the xfab for around 5k http://www.dwslab.com/...

I have a good many years of working with Abaqus but mostly with structural, quasi-static analysis etc but not much thermal. Right now I have a more or less simple thermal model that I am trying to correlate to measured performance and I fear my unit consistency may not be correct for some of the...
