Abstract

This article reveals some implementation details regarding the C code of the revised table interpolation blocks released with the Modelica Standard Library (MSL) 3.2.1. The emphasis is placed on the unique features of the CombiTimeTable which are the discontinuities by time events and the periodic extrapolation. Basic information on the interpolation by Akima splines and the available table array memory optimization options are mentioned.

Keywords

univariate interpolation; bivariate interpolation; periodic extrapolation; time events; Akima splines
