Dear Taufik

I tell you how I get the electric field for BANDRF.

I get the data from ANSYS, and then I have to get a file compatible with ascii2h5block_asgic.cpp. So, I've develop a MATLAB program to interpolate the data to cartesian coordinates employing the properly mesh that I want for my h5part file. I could provide you an example of this file, if you need it. Then, I run cpp program with the properly limits and size of the mesh.

Thank you.
How is the format of the electric field data from the TOSCA? Should I get the data from the TOSCA at  the points of a polar coordinate and write the data in the Cartesian coordinate?

Best regards,

Dear Pedro Calvo Portela,


Thank you. I installed OPAL from binary distribution. In OPAL 2.0.2 version, there is src folder but it's only empty folder. Meanwhile, there is no such folder In the OPAL 2.2.0. So how to get ascii2h5block_asgic.cpp?

The file format needed in TYPE=BANDRF is h5part. You can convert any ascii data file to h5part with the cpp program found in src/tools/BandRF/ascii2h5block_asgic.cpp, in your opal directory. You have to modify the geometric limits of the region of the electric field and the mesh inside this file

Dear All,
I want to import Dee electric fields data for cyclotron particle tracking
simulation. From OPAL manual, it can be done by using TYPE=BANDRF.
However, I am still confused about how the 3D electric field data format
should be written. Can anyone help me with this case?
Best regards,
