Interpreting UDF on multiple HPC nodes!

supermanks · March 19, 2016, 20:18

Hello folks,

I have been running a dynamic mesh case along with an interpreted UDF on my windows machine and recently shifted some larger cases to a HPC cluster.

The cases work fine when I'm using 1 node (16 processors), and the UDF interprets perfectly. However, when I try to scale my setup with 2 nodes, I encounter the infamous "syntax error: line 1" message where "line 1" corresponds to the header directive, "#include "udf.h"".

I've spent almost the whole day looking at other users' posts here and tried all possible fixes (for eg. the "dos2unix" command), but I'm not totally sure why the UDF would interpret on 16 processors, but throw out an error while I expand to 32 processors (2 nodes). (I assure you my UDF is a very simple inlet condition, and almost similar to the one in the fluent UDF manual.)

Any quick ideas or help would be greatly appreciated, thank you!

Regards
