this UDF code is for computing the melting index along a particle trajectory.<\/p>\n

this code has been tested in 2d and 3d cases in the DPM model.<\/p>\n

what I tried to achieve is by using this code to obtain the particle locations of 10 particles with respect to time.<\/p>\n

based on my understanding, this code just records ONE particle location and writes them into a file (melting_output).<\/p>\n

I copied the code and pasted it into txt file. I hooked it up in DPM model.<\/p>\n

the code could be compiled but when DPM iterates, then I this SIGSEGV error.<\/p>\n

I used a linux server to run fluent case.<\/p>\n

I searched it; it is said this error shows <\/p>\n

“SIGSEV tends to be network related, but may be triggered by something else in the solver: it’s not an error we can diagnose as such. What did the TUI show just above all of that lot? That text may be more useful.” from Rob.<\/p>\n

the model works before using this code.<\/p>\n

 <\/p>\n

how to debug this kind of error?<\/p>\n

Thank you.<\/p>\n
