Fluent eror
Now I want to simulate the phenomena of phase change and fluid flow in heat pipe with Fluent. When I initialize the solution, an eror appeared as follow:
Error: FLUENT received fatal signal (ACCESS_VIOLATION) 1. Note exact events leading to error. 2. Save case/data under new name. 3. Exit program and restart to continue. 4. Report error to your distributor. Error Object: () In this simulation, I want to use UDF of evaporation and condensation as follow, Would anyone help me checking it? #include "udf.h" #include "sg_mphase.h" #define T_SAT 298 #define LAT_HT 2442 DEFINE_SOURCE(liq_src, cell, pri_th, dS, eqn) { Thread *mix_th, *sec_th; real m_dot_l; mix_th = THREAD_SUPER_THREAD(pri_th); sec_th = THREAD_SUB_THREAD(mix_th, 1); if(C_T(cell, mix_th)>=T_SAT) { m_dot_l = -0.1*C_VOF(cell, pri_th)*C_R(cell, pri_th)* fabs(C_T(cell, mix_th) - T_SAT)/T_SAT; dS[eqn] = -0.1*C_R(cell, pri_th)*fabs(C_T(cell, mix_th) - T_SAT)/T_SAT; } else { m_dot_l = 0.1*C_VOF(cell, sec_th)*C_R(cell, sec_th)* fabs(T_SAT-C_T(cell,mix_th))/T_SAT; dS[eqn] = 0.; } return m_dot_l; } DEFINE_SOURCE(vap_src, cell, sec_th, dS, eqn) { Thread * mix_th, *pri_th; real m_dot_v; mix_th = THREAD_SUPER_THREAD(sec_th); pri_th = THREAD_SUB_THREAD(mix_th, 0); if(C_T(cell, mix_th)>=T_SAT) { m_dot_v = 0.1*C_VOF(cell, pri_th)*C_R(cell, pri_th)* fabs(C_T(cell, mix_th) - T_SAT)/T_SAT; dS[eqn] = 0.; } else { m_dot_v = -0.1*C_VOF(cell, sec_th)*C_R(cell, sec_th)* fabs(T_SAT-C_T(cell,mix_th))/T_SAT; dS[eqn] = -0.1*C_R(cell, sec_th)* fabs(C_T(cell, mix_th) - T_SAT)/T_SAT; } return m_dot_v; } DEFINE_SOURCE(enrg_src, cell, mix_th, dS, eqn) { Thread *pri_th, *sec_th; real m_dot; pri_th = THREAD_SUB_THREAD(mix_th, 0); sec_th = THREAD_SUB_THREAD(mix_th, 1); if(C_T(cell, mix_th)>=T_SAT) { m_dot = -0.1*C_VOF(cell, pri_th)*C_R(cell, pri_th)* fabs(C_T(cell, mix_th) - T_SAT)/T_SAT; dS[eqn] = -0.1*C_VOF(cell, pri_th)*C_R(cell, pri_th)/T_SAT; } else { m_dot = 0.1*C_VOF(cell, sec_th)*C_R(cell, sec_th)* fabs(T_SAT-C_T(cell,mix_th))/T_SAT; dS[eqn] = 0.1*C_VOF(cell, sec_th)*C_R(cell, sec_th)/T_SAT;} return LAT_HT*m_dot; } |
