What is the name of the sefer that discusses the types of punishments given in gehennim?
It's an old sefer and we can't remember the name.

Collating answers from the comments in addition to my own:
Regarding this last suggestion @N.T. wishes to point out that R. Yosef Karo maintained that this work ought not be read (see SA:OH 307:12), however others such as the Ramhal praise it and its author and it is similarly cited by R. Yehudah Aryeh mi-Modena, R. Eliyahu Behor, and the Yashar mi-Kandia (for discussion see here). It is also worth pointing out that the liturgical poem Yigdal is likely an adaptation from this work (fourth chapter). As a question of personal practice, consult a competent halakhic authority.
