Hi everybody, I need to access to volume of fluid gradient and temperature gradient to use as a source. I am using Eulerian model. Fluent compiles well but when I try to iterate it gives me this 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: () The code is: #include "udf.h" #include "sg.h" #include "sg_mphase.h" #include "flow.h" #include "mem.h" DEFINE_ADJUST(area_density, domain) { Thread *t; Thread **pt; cell_t c; Domain *pDomain = DOMAIN_SUB_DOMAIN(domain,P_PHASE); real voidx, voidy, voidz=0; { Alloc_Storage_Vars(pDomain,SV_VOF_RG,SV_VOF_G,SV_N ULL); Scalar_Reconstruction(pDomain, SV_VOF,-1,SV_VOF_RG,NULL); Scalar_Derivatives(pDomain,SV_VOF,-1,SV_VOF_G,SV_VOF_RG, Vof_Deriv_Accumulate); } { Alloc_Storage_Vars(domain, SV_T_RG, SV_T_G, SV_NULL); T_derivatives(domain); Free_Storage_Vars(domain, SV_T_RG, SV_NULL); } mp_thread_loop_c (t,domain,pt) if (FLUID_THREAD_P(t)) { Thread *tp = pt[P_PHASE]; begin_c_loop (c,t) { C_UDMI(c,t,0) = (C_VOF_G(c,tp)[0]*C_T_G(c,t)[0]+C_VOF_G(c,tp)[1]*C_T_G(c,t)[1]); } end_c_loop (c,t) } Free_Storage_Vars(pDomain,SV_VOF_RG,SV_VOF_G,SV_NU LL); Free_Storage_Vars(domain, SV_T_G, SV_NULL); } DEFINE_SOURCE(gas, cell, thread, dS, eqn) { real x[ND_ND]; real source; Thread *tm = THREAD_SUPER_THREAD(thread); Thread **pt = THREAD_SUB_THREADS(tm); source = -0.6*(C_UDMI(cell,tm,0)/40); C_UDMI(cell, tm, 1) = source; dS[eqn] =0; return source; } DEFINE_SOURCE(liquid, cell, thread, dS, eqn) { real x[ND_ND]; real source; Thread *tm = THREAD_SUPER_THREAD(thread); Thread **pt = THREAD_SUB_THREADS(tm); source = -C_UDMI(cell, tm, 1); dS[eqn] = 0; return source; } |
