Dear Guoliang

 

Both png files look not so promising. Anyway, I am not so familiar with this kind of output. I normally use the program VisIt to look at the E- and B-fields in h5part format visually. Of course, the decisive prove should be the tracking through the map itself. For instance, it should give the right energy gain, or the right deflection to the beam, or some other criteria.

Best wishes,

 

Hui

Subject: [Opal] Field Output Command

 

Hi,all

 

After I imported the 3D electric field simulation, I wanted to check whether the electric field read by OPAL and used for calculation was correct. 

 

I noticed gnu.out and eb.out in the data folder, but the electric field in eb.out was always 0. (attachment 1)

 

I also tried to modify INFO, TRACE and EBDUMP Option Command, but got no output results. I also notice the DUMPEMFIELDS in the Field output command, but the electric and magnetic fields in output file still are 0.（attachment 2）

 

Anyone has any suggestions?

 

Best wishes,

Dou
