Solidworks Simulation Linear Dynamic Material Density

[ChowChow89]

Most material property data given by a manufacturer or material handbook are in "weight" density (lb/in3)


For a static study, like applying pressure, the density is immaterial, whether it is in "weight" density or "mass" density.

However, when inputting values for custom material in Simulation when starting a Linear Dynamic Study (an acceleration g loading (External Loads ->uniform base extraction)) as an example, do we use "weight" density (lb/in3) or "mass" density (slug/in3)?

I know SolidWorks Simulation uses the wrong wording. Simply look at the units SolidWorks Simulation uses for their density and follow the units; not the name they chose to use for it.

lb/in3 is what it uses I think, but they call it Weight density. So just ignore the improper name.

Thank you for your input KeinDeSmet. I looked further into the mater and came to these conclusions.
In the past (Geostar) the input density was Specific Weight (or Weight Density). γ = ρg

Solidworks Simulation uses Mass Density lb/in^3. ρ = m/V
