Hello Tan Shi,
Looks like rQMD is not linked.
You must first build a new executable $FLUPRO/flutil/ldpmqmd -o executable_name
Then run with the executable $FLUPRO/flutil/rfluka -N0 -M1 -e executable_name input_name
You can also do this using flair.

Badly treated means that the simulation is not done with the most appropriate model. In your case there is a possibility of having ions with energy above 150 MeV/n without applying rQMD model.
Best regards,
George

Hi,
Thanks for your reply. After adding IONSPLITting, the code can run till the end but in the .err file, it says:
"Coalescence activated and beam above BME limit, products badly treated with IONSPLIT
link rQMD !".
Again, the existing answers do not really explain clearly what it means by "products badly treated with IONSPLIT". Here is my input setting for IONSPLITting:
PHYSICS 1. 1. 2. 220. 1.IONSPLIT
Thank you for your help!

Dear Tan Shi,
The IONSPLIT option was improved even before FLUKA-2020, since FLUKA-2011-2x.

The bottom line is that if you are studying activation by GeV electrons, you must link RQMD and DPMJET to prevent simulation of energetic ions without appropriate interaction model. May not be a significant factor, depending on your problem, but it is still required. Instructions on how to do this:

Subject: [EXTERNAL] [fluka-discuss]: Question about difference between Fluka2020 and Fluka2011 in Ionsplitting (for activation study)
Dear Fluka experts,
After I updated to Fluka 2020 (with "flukadpm3" installed), I came across the following error: "Coalescence activated and beam above BME limit with no rQMD and no or incompatible IONSPLIT option!". However, the same input file works fine with Fluka 2011. I have seen several questions related to this error, but I still do not fully understand the underlying cause. I attached the relevant physics cards in my input file. I also used several commands related to radionuclide decay since I am simulating activation induced by high energy electrons (~GeV). Should I add other physics processes such as IONSPLITting here? Thanks for the help!
PHYSICS 3. EVAPORAT
PHYSICS 1. COALESCE
Best,
Tan Shi
