Description of problem:
The customer has an input function with two input points that are only
separated by .001 but the Y points are distinctly different. When generating
the response at the input node, the response graph appears to skip over one of
the two points and the response is missed. Is there a tolerance associated
with the interpolation of points during the evaluation process in Response
Simulation?
Solution
During the interpolation process, there is a check for a small frequency
difference to determine if a frequency is close enough to the last one to be
skipped. The tolerance is hard coded and it's value is 0.001 Hz. So, there is
a tolerance used for the interpolation and combining of frequencies when using
an Uneven Event.
A work around would be to use excitation frequencies that are separted by more
than .001 HZ.
