ECHO2D: release of version 3.2

ECHO2D: release of version 3.2

Version 3.2: a bug of mesh creation in ECHOz1 and ECHOz2 is fixed; small changes in GUIs; the manual is updated. The example with inconsistent results was found by Jean-Yves Raguin (PSI). It was a bug in the mesh creation. Following my debugging expierence with this example I have placed the following text in the manual. “The codes use a conformal finite-difference method. In the time-domain wake field calculations the mesh resolution with 5 mesh points on the rms bunch…

Wall conductivity in ECHOz2 and ECHO2D.

Wall conductivity in ECHOz2 and ECHO2D.

As default mesh use 5 mesh lines on sigma in vacuum and “NStepsInConductive=10” in metal. It means that the skin depth in the metal will be meshed with 10 mesh lines. If you increase the mesh density in vacuum by factor 2 (10 mesh lines on sigma) you should simultaneously increase by the same factor “NStepsInConductive” in metal: “NStepsInConductive=20”. It means that the calculation depth in the metal remains the same. For 20 mesh lines on sigma use ”NStepsInConductive=40” and so on. …
