Hello,

this is maybe a stupid question, but just to be sure.
Suppose my model is representing a microstructure with chosen unit-lenght "micrometers = 10^-06 m = 1 um".

should I also accordigly express the Young's MOdulus and all the stress values in N/um²?

for example from a typical value of E in Pascal of
400 GPa = 400 *10^9 N/m²

should I put (in the material definition)
400*10^9 N/m² * 10^-12 m²/um² = 400 * 10^-3 N/um² ?

I think the only important think is consistency of units, so it is not mandatory to use Pascal in this case, right?

many thanks, Alex

Yep, and your results will be in the same units, ie. micrometers and Newtons per microdiddlymetres squared.
