3 months ago There's a few issues with your input deck, lines such as t_end = 10femto should be replaced with t_end = 10*femto. Also, note the warning:
*** WARNING ***
Input deck line number 7
The constant block variable "t" conflicts with a
built-in constant name. It will be ignored.I can't test the full set-up as I don't have access to the injector files you are using. That being said, I have no problem parsing the injector section of the input deck. What version of EPOCH are you using?

I use the file injector in input.deck, but unrecognised element "inject_from_file" ,"y_data" ,"py_data" when running the input.deck. I don't understand why unrecognised element "inject_from_file" ,"y_data" ,"py_data" of injector block. Below is my input.deck.
