Emily's Favourite Error Messages


This page is a place for storing error messages so I can compare and contrast.


Nicholson Canyon viscous3D parallel runs

I get the same message on both turbine and the new modelling computer and it occurs at the same position:

The same code runs in series, I also tried with 2 and 4 cpus and it failed with the same error message (although at t=1 for 4 nodes and before writing any output for 2 nodes. It seemed to be consistent when it failed.


--- Gerris Debugging When running gerris debugging after the fact (i.e. as Stephane suggested doing the following)

I get:

When I remove the remove droplet command this seems to fix the problem


Parallel runs of solid block scenario

I have problems with running the solid block example too. Prior to dying I often (but not always) get the following warning:

Gfs-CRITICAL **: PE 0 (NIWA-36411): gfs_line_center: assertion `a > 0. && a < 1.' failed

The following was generated using the debugging suggestion above. This was running on a 8 core modelling computer. Looking at the core dump using gdb I get:
