Failure in parsing "AKISPL(,0,301001)"

Hello,

I've been trying to input acceleration data acquired during RLDA as a 2D curve from a .csv file. I have been encountering parsing error.

ERROR: Failure in parsing "AKISPL(,0,301001)"!

Can anyone please explain why this error is occurring and how to mitigate it? Also please share tutorials for standard practices while handling such data. Thank you for your time.

Hello Niraj

The AKISPL statement that I see looks suspicious. It is missing the first argument. The expected syntax can be found here.

Could you please verify either in the XML or in Motionview that there is a first argument provided ?

Hi Niraj - To add to Praful's suggestion above, can you double-check that you made the curve available to the Motion or Force entity that is applying it to the wheel center? Attaching a model will make diagnosis easier.

That said, sometimes Akima interpolation can fail on test data. You will need to try other interpolation methods like Linear (most likely to succeed, and likely the best option if the sampling rate was high enough), or Cubic. One way to verify the interpolation is working correctly even before you run a model is to go to the visualization tab in the Curve panel, check Interpolate box and use the desired interpolation method that you are using where the curve is applied.
