ProMechanica Mass in Nmms units?

[guym]

Hello,

Does anyone know what the ProMechanica Mass in Nmms units is?

Is it (N.s^2 / mm ) = 0.1*Kg * 1000?
Therefore having to /9.81 and * 100 to get the unit in kg?

Thanks

I think actually, the unit for mass is the metric tonne.

So multiply the value by 1e6 should give grams

Can anyone confirm this?

Thanks

Guy

What is your application? If you are using Nmms, which means you are living in a Force world. So if you have a cantilever beam with a load on the free end, the load would be in Newtons = kg x m/sec^2. You use mass when you define the density of the model, however, you can choose any units you like including Kg/m^3.

Fortunately Mechanica has supported mixed units in the UI for a while now, so your inputs can be whatever you are comfortable with.

But yes, in a N-mm-S system of units, force is in N and mass is in tonnes.
