1. ## Hypergraph HIC Calculation Problem

Thank you for the quick responses. The method shown in the attached video ist exaclty the one that I have used. My problem is the graphical representation of the HIC "Curve" and the original acceleration curve. What I have is the HIC Curve leveling up to the maximum g- Value (the same as in your Video), however I want my diagram to look like this: Thank you in advance.
2. ## Hypergraph HIC Calculation Problem

After some recalculations I have found out that my HIC value is indeed correct. My only issue is the graphical representation of it. Is it possible to plot the corresponding HIC value on the second y-axis in such a way that it is proportional to the g- scale on the left y- axis?

4. ## Hypergraph HIC Calculation Problem

I have tried both with Hypergraph 14 and Hypergraph 2017.
5. ## Hypergraph HIC Calculation Problem

I have a problem with Hypergraph calculating the HIC curve/ value for an acceleration problem. My steps were: 1) Import my simulation Data from LS-Dyna output files (acceleration (g) vs time (s)) (millimeter, second, tonne (LS Dyna output)) 2) File -> Load -> Preference File -> Vehicle Safety Tools 3) Injury -> HIC -> HIC Curve 4) In the HIC Curve Menu I selected my imported curve, plot to new window What Hypergraph now does is simply take the g_max value as the "top" of the curve, and adjust the time limits according to the HIC criteria. As a HIC value I obtain 195.107, which in my opinion is far too less, considering i have between 20-50g for 30ms. How does Hypergraph give out the correct HIC value? What details did I miss out? Thank you in advance.
