Default units

Hello,

When I want to review the stress results of an analysis, the stress units are default on "kPa". Is it possible to change the default to "MPa" instead of having to select it each time from the drop-down list? I can't find any option in the configuration editor to do so.

The same issue occurs when defining a force. The default unit is "mm kg / sec^2". I'd like to change this to "N".

I am using Creo Simulate 3.

Hi Wouter,

This may be dependent on your model base units (which are set in Creo, not in Simulate).

I prefer to set my models to "mm N s" - this has the small disadvantage of leaving the mass units as tonnes (and density as tonnes/mm^3), but makes MPa the 'native' stress unit, and obviously N as the force unit.

If you use "mm kg s" then the force unit will be mm.kg/s^2, as you've found - the force required to accelerate 1 kg at 1 mm/s/s, otherwise known as mN.  Similarly, stress will be mN/mm^2 which (if I'm right) works out to kPa.

At least Creo introduced the ability to select other units from a drop-down - in Wildfire you were stuck with the native units!

HTH!
