[aspect-devel] Floating Point Exception error for simple setup

[FELIPE ORELLANA ROVIROSA]

 Hi all,

       I am trying to run Aspect in parallel for 3D computations, and I am
getting errors related to 'floating point exception'. I know other people
in the community has suffered this same problem, in different situations,
versions and machines.

      For instance, I am using version 1.4.0-pre on TACC Stampede. When
trying to run the 3D convection example, after short running times I get
the error:


-----------------------------------------------------------------------------
-- This is ASPECT, the Advanced Solver for Problems in Earth's ConvecTion.
--     . version 1.4.0-pre
--     . running in DEBUG mode
--     . running with 256 MPI processes
--     . using Trilinos
-----------------------------------------------------------------------------

...

    Is there a vulnerability with the Aspect version I am using?
  or the problem lies on another issue?

    What would be the recommendation?

I greatly appreciate your help,
cheers,

Felipe
