Hi everybody
I am trying to write a reaction udf.
I got some error so I try to solve them meanwhile I try ti know what mw[][] give me. in help of fluent says that mw[][] is a matrix that give the molecular weights so I wrote this udf:
DEFINE_HET_RXN_RATE(user_Co, c, t, hr, mw, yi, rr, rr_t)
{
Message0(" %d %d %d ",mw[1][0],mw[0][0],mw[2][0]);
*rr = 1 ;
}
and run it for 1 itrate for a very simple problem of air and water and I did not change any fluent data base so I get this results:
-1073741824 1077737291 536870912
and this numbers are not water or air monocular weight do you have any idea about my work and can you tell me what is mw[][] give me?
thank you
