How does a piecewise linear function handle values outside of points included?

      Hi, I implement a piecewise linear function (viscosity versus temperature) to describe a material property. I include 10 points. The lowest point is at temperature 300 K with value 20 Pa*s and highest at temperature 400 K with value 60 Pa*s. What value does ANSYS take for values outside of the points included? Does, for example, ANSYS take 20 Pa*s for every value under 300 K, and 60 Pa*s for every value above 400 K?

      Thank you for helping out!

      Hi Yannice, please let us know what Ansys product you are asking about.  The answer could be solver specific i.e. Mechanical APDL may have a different answer (generally speaking) than say Fluent.  Mike

      Hi Mike, thank you for your reply! I use Fluent (and Workbench 2021 R2)
