enlarge scale on post processor? Units? was created by Arlen Nelson
they don't show this in the tutorial, but is there a way to enlarge the results scale, it is too small to read.
** edit figured out the scale... but what units are these?
If using the wizard i input MPa... my base units out would also be Mpa?
my scale stats at 200 and finishes 18.9
that is 200 mpa and 18.9 gpa? which sounds wrongs
so pa, and kpa?

Hello Arlen Nelson,
As in ALL FEA software, the units in any post-processor are dependent upon the units used for the inputs. So examine the units you have used for mass, dimensions, Young's Modulus, etc. then arrive at the consistent units for the stress.
One set of units can be:
g,mm,ms,N,MPa,N-mm (Mass, Dimension, Time, Force, Stress & Energy)
where for steel: Density & Young's Modulus would be 7.83E-3 and 2.07E+5 respectively.
Regards,

In the table below a set of units is given that can be used for FEA.
Of course it is not complete but it has been very usefull to me.
It has the advance that the frequency (and hence 1/time) is in [Hz].
[code:1]
quantity 1-SI 2 3
length L [m] [mm] [mm]
displacement u [m] [mm] [mm]
time t
frequency f [Hz] [Hz] [Hz]
mass m [kg] [10^3 kg] [g]
inertia Iij [kgm2] [gm2] [gmm2]
force F [N] [N] [µN]
density rho [kg/m3] [10^3kg/mm3] [g/mm3]
gravity a [m/s2] [mm/s2] [mm/s2]
Youngs’ module E
pressure p [Pa] [MPa] [Pa]
stiffness C [N/m] [N/mm] [mN/m]
[10^3 kg] = [ton]
[10^3 kg/mm3] = [ton/mm3]
[/code:1]
