Dear Riya Dey,
I see in your screenshot that you are generating an enormous .err file
(about 2.8 GB)... with parallel 10 subdirectories you fill your disk space
in few minutes (as I see). To understand your problem please look at this
.err file.
Kind regards,
Anna

I am using a system with 40 GB disk space. I am attaching one screenshot of the size of the output files. Is this problem occurring due to the source file ? Or is there any unnecessary big file generating during the simulation?

>>Helloit is very difficult to debug user routines, especially when not all theelements are available (dada file).From the log file, you can see that the problem is indeed in your source.froutine.I suspect that something goes wrong in the calculation of the z cosine,resulting in a squareroot of negative value. This can come from roundingof the other two cosines, maybe written to disk with too few significantdigits.Maybe it would be better to keep all the three of them as read from thedata file, and apply a normalisation a posteriori on all three.But, of course, I am not sure that this is te reason. You can again printvalues (only for the cycle that crashes) and/or inspect the core file withthe gdb linux utility.

If yess, the readstatementis not correct: at each READ, one record will be load , I mean one line,and only one quantity will be read in from this record, the first one,andassigned to A(i). Thus, the code will try to read 1946728 LINES, not1946728 values.Again, if my assumption is correct, you can do two things:A loop on 243341 lines, reading 8 separate vectors (which will makethingsmuch easier) : read (30,*) x(i),y(i),z(i),E(i),wt(i),u(i),v(i),w(i)A single read, without loop : read(30,*)AI suggest in both cases to add prinout lines to check that everything isworking correctly.regardsPaola
