ECHO3D is updated
The package ECHO3D is updated. The mesher is parallelized with threads. A GUI bug is fixed. A new example is added.
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.
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. …
ECHO1D: update to version 1.2
The package ECHO1D is updated to version 1.2. The algorithm is changed to avoid overflow errors for high conductive materials. The width of high conductive layer should be comparable with skin depth.
ECHO2D: GUI version is updated
GUI version of ECHO2D is updated. Minor changes.
ECHO3D: version 1.2. Many materials. Manual update.
The package ECHO3D is updated to version 1.2. It is possible to use many materials now. A version with GUI interface for Windows is compiled. New manual with section about ECHO3D uploaded. The conductivity will be implemented in the next release.
ECHO2D: Linux version.
I have compiled the code ECHO2D for linux. It is thread parallelized. The number of threads is equal to the number of modes. If only one mode is calculated then the code is serial and it will be slower than ECHOz1 or ECHOz2 where the one mode calculation is thread parallelized. The linux version can be found at directory Codes/Linux. The examples can be executed with the script run.sh available in the local directory ECHO2D of each example. In the…
ECHO2D: version 3.1. Manual update.
The package ECHO2D is updated to version 3.1. New features: 1. ECHOz1 and ECHOz2 are thread parallelized. 2. ECHO2D allows to use many materials with different permittivities, permeabilities and conductivities. 3. ECHO2D allows different shape of bunch. 4. Field monitors in ECHOz2 and ECHO2D. 5. Wake monitor in ECHO2D. Manual is updated as well. In the next update I will describe how to do particle tracking and waveguide port setup. The executables are for Windows. the code ECHO2D can be…
ECHO3D: version 1.1. Thread parallelized.
The new version 1.1 is thread parallelized. I have removed GUI from the code. The input file is unique now for all steps: meshing, initial fileds, calculation … The short version of manual can be found as PPTX file in the archive itself. The code can be compiled for Linux/MacOS on request.
