About Units
The software allows you to choose the units for defining analysis features
and viewing the results. Each PropertyManager or Dialog box, that requires
input with units, allows you to use the default or different units. For
example, you can choose SI as your preferred system of units, specify
pressure in psi, displacements in millimeters, view the displacement results
in inches, and stress results in N/m2.
You can specify your preferred units for length, temperature, angular
acceleration, and stress independently. For example, you can select Metric,
which uses centimeters as the unit of length, as your preferred system
but choose inches and Fahrenheit as the length and temperature units,
respectively.
To set default units:
Click Simulation, Options.
On the Default
Options tab, select Units.
Under Unit system,
select a unit system. The selected unit system is used by default for
quantities other than the quantities specified in Units.
Under Units,
select specific units for Length/Displacement,
Temperature, Angular
velocity, and Pressure/Stress.
Click OK.
