Question:
I'm trying to determine the effects of changes in vehicle stiffness coefficients in a SIMON/DyMESH event by going back to the Vehicle Editor and changing the values for A & B in the Stiffness dialog, but I'm not seeing the changed values reported in the Vehicle Data report. What might I be doing wrong?
Answer:
In HVE, the new Vehicle Exterior Stiffness dialog has a Type selection for 2-D or 3-D. When 2-D is selected, only the classic A and B values are available to edit. When 3-D is selected, the coefficients for a full quadratic stiffness behavior are available. In HVE, it is important to remember that EDSMAC4 uses values from the 2-D setting, while SIMON/DyMESH uses values from the 3-D setting.
