Calculating NIJ in DIAdem 2014

[rvillalta319]

Hey All,

I want to calculate NIJ for some upper-neck load data that I have collected on a Hybrid III 50th percentile dummy. I can easily use the crash analysis tool to process the calculation (see screenshot and code below), however, I am hoping to get some clarification on what DIAdem expects as inputs.

This results with the following scripted code:

Call ChnNijCalc("[1]/Time axis","[1]/Upper Neck Force Z1","[1]/Upper Neck Moment Y1","[1]/LoadCondition",6806,-135,"NTE")

DIAdem's help provides the following information on NIJ:

My questions are:

1. Do I need to calculate the MOC myself and choose that as the input channel for the Moment My? Or does DIAdem calculate the MOC automatically? I know and understand that the MOC calculation varies per dummy type. So the way I see it, it should be easy for DIAdem to calculate the appropriate MOC since I have chosen the critical inputs (Fzc & Myc) specific to my dummy type (Hybrid III 50th). I feel like I need to calculate it myself, but just want to be sure.
2. Should the units for my Force and Moment be (N) and (Nm) respectively?

Thank you all in advance!

Hi, im using the ChnNijCalc() function as well. As inputs i add channel with force having kN units and second channel is the moment, which should have Nm units. Depending on type i add parameters from the table in help depending on dummy.

As this works for me, i didnt calculated it manually.
