Subject: Re: Distributed Ansys: Multiple Result Files?
Author: Richard Wang

Distributed run divides the model into different parts (number of cpus)
and solves them separately using each cpu to get each part of solutions,
i.e., jobname1.rst, jobname2.rst, .... After all the solutions are done,
the individual result files are combined to piece together jobname.rst
from which results can be postprocessed. However, what's puzzling me is
that if the simulation is terminated abnormally, either by computer
crash or manually stop, the final result file jobname.rst cannot be
formed and results cannot be postprocessed. Also, it seems to me that
using the distributed mode does not save significant run time. For
example, as I observed, running the same job on a 4-core computer
distributedly and running it distributedly on three 4-core computers
required almost the same amount of run time.

Subject: [Xansys] Distributed Ansys: Multiple Result Files?

I'm new to using Distributed features within Ansys and when solving I'm
a little confused regarding the result files which are put out. I'm
using four processors to solve and five results files are produced in
total. They are Jobname.rst, Jobname0.rst, Jobname2.rst, etc. Whenever
the solve is done and I go to post process results I'm unable to view
jobname.rst. I forget the exact error which it kicks back...something
about no results I believe. However, I can view the individually
numbered result files which contain results for a portion of the model.
Does anyone know how I can get Ansys to view all results simultaneously?

Thank you,
