thanks Jochem

I convert my file with python.

Now I get this error

OPAL> * Read both median plane B field map and 3D E field map of RF cavity for compact cyclotron1
OPAL> * Reading e-field_1cmed.h5part

Can you guide me?

Dear f66.panah,

Attached is a C-program and Readme that converts an ASCII output to the h5 format, it can also be found in the repository under tools/BandRF. You might need to adapt it to your use case as it was written for ANSYS output files.

Hope that helps,
Jochem

Hi everyone,
I am using OPAL to simulate cyclotron.
I can import magnetic field from OPERA by text format (.txt).
Now I want to import an electric field from CST which is a text file. I know
the electric field file must be in h5part format and I should convert the txt
file to h5part. But I don't know how should I define its structure. My text
file consists of some columns for positions (‘x’,’y’,’ z’) and electric field
values (‘Ex’ , ‘Ey’ , ‘Ez’).
Also, how can I define the steps and position of data?
Any help is appreciated
