Running a CFX simulation on the cluster

saisanthoshm88 · October 22, 2011, 12:01

I had an error while running a .def file in CFX on a cluster. I don’t have any prior experience in setting up the run on a cluster. Attached to this post is an image of the error encountered.
Could some one please look into it and suggest upon overcoming this problem

Usually this means the cluster had a glitch, some packets were lost and the run crashed. Check why the network had a glitch.

Thanks for the reply Glenn, Could you please tell me the command used to start the CFX run in a Partition Mode with User Specified Direction

I was searching for this in the help manual but couldn`t find the command related to User Specified Direction , however I could find it with other in built partitioning algorithms like : Optimized Recursive Coordinate Bisection , Directional Recursive Coordinate Bisection

This is from the output of "cfx5solve -help", guess it is also in the manual.

change directory:
-chdir <directory>
Set the working directory as specified.

partition mode:
-part <number of partitions>
Run the ANSYS CFX Solver in partitioning mode. This option should not
be used if an existing partition file is also specified.

Thanks Lance, it worked with an existing partitioned file
