Dear ALL,

I am developing some law (devolatlisation and combustion ) for biomass combustion. There are total of 7 new laws, which have been tested individually and working fine.

However, when I want to use them together for a combusting particle in certain order, FLUENT is allowing me to use 4 new laws only. It is developing an error "DPM - unknonw heat/mass transfer law - 12 ".

I did figure it out this as a problem of number of laws it can use at maximum.
I mean 1- heating (def),
2-evaporation(def),
3-boiling (def)
4-heating(def)
5-devolatlisation (def)
6-combustion(def)
7-heating/colling(def)
8- USER_DEFINED LAW1
9-U_D_LAW2
10-U_D_LAW3 etc..
I tried to used define_dpm_switch to override the default laws with new one. Did any one know how to override it or to use DPM_SWITCH?

Thank you for your help.

Regards
Sree
