Material properties units Simlab

RokHodnik

Hello!

One quick question.

 

When inputing units into materials manager in Simlab I often have problem with knowing in what units to input the property data.

 

For example is the unit for Density kg/m^3 or g/mm^3 or kg/dm^3 or kg/mm^3?

 

In tutorials people are usualy inputing data in XX units for example for steel 7.8e-9 units.

 

Steel has:

7650 kg/m^3

0.00765 g/mm^3

7.65 kg/dm^3

7.65 e-6  kg/mm^3

 

So what is the input unit?? I think it is kg/mm^3 but then tutorials input false data.

 

Specific density SI unit is kg/m^3.

 

Below is example from tutorial.

Calculating Mass property confirms the 7.65e-6  kg/mm^3. Please confirm my statement.

The modeled structure sholud have cca. 200g of mass.

 

Input density in this case is 7.65e-6  kg/mm^3.

 

Still confused with tutorial input data and default input data in the box. As 7.8e-9 density is not used for any material why should it be default value...
