I am writing to inquire about the best way to configure freeradius for eap-sim.

That's good.
How would I configure freeradius to use the Ki and OP when it receives a message from the test peer requesting to authenticate with EAP-SIM?
You just tell the server what they are, and the server does the right thing.
I tried putting the Ki and OP in the users file but that didn't work.
What does that mean?
According to doc/modules/rlm_eap it says I need to write a separate module to generate GSM triplets given the Ki. However, in src/modules/rlm_eap/types/rlm_eap_sim/rlm_eap_sim.c:eap_sim_get_challenge it looks like there is already a module to generate GSM triplets given the Ki. How could I configure freeradius to call it?
To be honest... this isn't a commonly used feature. :( From a quick check of the source, you put the EAP-SIM-* attributes into the "control" list, and it *should* just work. Alan DeKok.
