I am writing a udf for the volumetric rate: the vr rate is defined in terms of one of the concentration of the reacting species using Arrhenius eq , so after first time step the new concentration will be the concentration after rate calculation, will it update automatically or i have to specify some thing !
real temp= C_T(c,t); Y_fe2o3=C_YI(c, t, 0);/*mass fraction*/ X_fe203=Y_fe203*C_R(c, t); /*( kg/m3 )*/ if (!strcmp(r->name, "reaction-1")) { *rate= -((28.432*pow(10,17))*exp(-607*1000/(8.314*temp))*X_fe2o3);/* kg/m3-sec*/ *rr_t=*rate; } } Kindly help me out ............thanks a lot in advance |
