Dimensions of the melting pool with high accuracy #23

Open olegrog opened 6 years ago

olegrog commented 6 years ago

So far, a quite crude algorithm is employed to calculate dimensions of the melting pool:

  1. Find a mesh point with the maximum coordinate along specified axis inside domain phi<1/2
  2. Find the nearest mesh point outside phi<1/2, but along the same axis
  3. Based on the linear interpolation, find a point, where phi=1/2 exactly.

However, the found point does not correspond to the extreme point of the surface phi=1/2. In order to find it, derivatives of phi can be used.
