Using load curve function for mass flow rate in AIRBAG_WANG

Using load curve function for mass flow rate in AIRBAG_WANG_NEFSKE

  I am trying to sum two curves together to get the correct mass flow rate to be used with AIRBAG_WANG_NEFSKE (lcmt). When running the simulation, the curve function works correctly (I am able to see the result from curveout), but there is no mass flow applied to the airbag. Is there a way to be able to use a curve function for lmct?
  Thanks,
  Kyle

  Hello Kyle,
  thanks for reporting this. I ran a test and I think you are right. If *DEFINE_CURVE_FUNCTION is used for LCMT, the bag does not inflate. Can you avoid using a curve function?

    Hi Andreas, thank you for looking into this. It is possible for me to do that calculation myself and run without using the function. However, my goal is to run a large number of simulations in which the load curve function would be extremely useful.

  Hello Kyle, the feature has been added to the latest R13, R14, and DEV versions.
  If you can open a Service Request on https://support.ansys.com/, we can send you an executable containing this feature.
