I used the Dicom function to generate a voxel model in Flair, but there were too many regions in this voxel model, which makes it unable to run. To this end, I added the global card, but it still doesn’t work properly.
if you look at the error message it says “GLOBAL out of order”. This does not indicate a memory problem but rather a problem of sequence of the cards. The GLOBAL card must be at the top of the input before other cards. See:
What you show is not the problem but the effect of the problem.
The program crashed and therefore generated a core.
Why did it generate a core? Nobody can tell with so little information.
What you have to do is to:
1-go inside the fluka temporary directory, in this specific case fluka_22021 and you can do that double clicking on it in the windows you are sharing
2-look inside the .log .err and .out file and search for error any message; this error message is likely to tell you what the cause of the problem is.
Extremely warmly invite you to review two lectures from the fluka beginners course:
the Flair introduction, to understand the basic concepts about running fluka and the files it generates
