Simple Serial to Parallel UDF conversion Fluent

amir00251 · August 29, 2015, 21:14

Hi everyone,

I am new to UDF and I need help on converting below simple UDF to parallel processing compatible.

#include "udf.h"

DEFINE_SDOF_PROPERTIES(box, prop, dt, time, dtime)
{
prop[SDOF_MASS] =20;
prop[SDOF_IXX] =200;
prop[SDOF_IYY] =300;
prop[SDOF_IZZ] =300;

}

thank you.

This code should also work in parallel. just ensure you are compiling ur udf.

For parallel case, care is taken while summing or global reduction operations.

Good luck.

Hi, thank you very much, as you said problem was about settings of UDF compilation not with parallel processing.
