Problems running the example

#1 Post by Andrea_Costa » Mon Feb 17, 2014 9:39 am


I compiled LTRANS and tried to run the analysis of the example file.

This is the screen output I obtain:

******************** Model Info ********************

****** BEGIN ITERATIONS *******
write output to file, day = 4.16666666666666644E-002

At this point the program is stuck and does not complete the analysis.

I tried to understand which steps the program was passin through so I put a counter at the beginning of the particle loop and at the beginning of the advection one.
So I figured out that before writing the first output file I have 30 particle loops (none of the which call the advection soubroutine). Then I have one particle loop that advects 303 particles and then another one particle loop that advects 126 particles. At this point the program is stuck.

I cannot figure out what the problem could be...

Please help! :)
