**Implementation of Particle Injection with Specified Velocity Distribution (e.g., Gaussian Distribution)**

[long9114]

Dear Developers,

I am currently utilizing EPOCH for particle simulations and require the injection of a particle population with velocities (or energies) following a specific distribution, such as a Gaussian distribution, without relying on external file input. It appears that the current implementation primarily supports injection through momentum drift configuration. May I inquire about the recommended approach to address this requirement?

Best regards,
