I'm using CCX finite elements analysis engine along with its pre- and post-processor CGX:
I'm looking at one example here that is using steel material:
In the example above, the declaration is done for Young’s modulus, Poisson’s ratio, and Temperature:
Mass density is initialized by:
Gravity, i.e. acceleration vector, is defined like this:
Therefore, the input values are:
- Young’s modulus =
- Mass density =
- Gravity acceleration =
What are the units of measurement for the above example?
I know the gravity acceleration is
9.8 m/s2. So,
But I'm confused about Young’s modulus and Mass density. What are their units? They should be consistent with the
mm. But I cannot figure them out.
This table from the latest CalculiX solver documentation helps with unit conversion. The units of the above example are
