Default vectorise DEFINE_VR_RATE ?
Posts: n/a
Hi !

I use the DEFINE_VR_RATE macro to calculate new reactions rates. But, for each iteration, this macro is called for each cell and each mesh has 2 700 000 cells and I treat 2 reactions : so, FLUENT call my UDF more than 5 000 000 times per iteration !! Therfore, the computation time is catastrophic !!

It is possible to vectorise the macros ? Or, does anyone got an idea to improve my UDF ?

Thanks a lot.
