錯誤：流利.14.5.7 UDF（SEGMENTATION VIOLATION）

我使用Fluent 14.5.7，並且在使用我的UDF時出現了一些編程錯誤。我試圖解決的模擬是在水平固定牀反應器中的脫硫過程。在包含UDF和CaO和SO2之間的反應之前，它可以很好地工作。我試着改變一些參數，返回一個常量值（用* rr = 60替換* rr = 60 * k * Beta * NSO2）和其他一些東西，但是同樣的錯誤出現了。錯誤：流利.14.5.7 UDF（SEGMENTATION VIOLATION）

這裏是我的C代碼：

/*********************************************************************/ 
#include "udf.h" 
#include "sg_mphase.h" 
DEFINE_HET_RXN_RATE(SO2_capture , c, t, hr, mw,yi, rr, rr_t) 
{ 
Thread **pt = THREAD_SUB_THREADS(t); 
Thread *tg = pt[0]; 
Thread *ts = pt[1]; 
real XCaO = C_YI(c,ts,0); /* Para checkear que hay sorbente*/ 
real XSO2 = C_YI(c,tg,0); /* Fraccion masica SO2 en la fase gas*/ 
real mwSO2 = 64.0638; 
real DENS_Gas = C_R(c,tg); /* Si hay problemas se puede considerar que es constante*/ 
real VReac=6333.843; /* Volumen total del reactor en cm³ */ 
real NSO2 = XSO2/mwSO2 * DENS_Gas * VReac; /* Controla el valor de NSO2 */ 
real Time_min = CURRENT_TIME/60; 

/*valores de constantes a 400ºC */ 

real EDiff = -49300; /*mejor sacar el negativo de la potencia*/ 
real aa1 = 2.10e-03; 
real aa2 = 12.9e-02; 
real aa3 = -0.66; /*mejor sacar el negativo de la potencia*/ 
real kdiff = aa1 * exp (EDiff/(8.314 * C_T(c,t))) * (1 + aa2 * exp (aa3*Time_min)); 
real aa4 = 0.82; 
real aa5 = -1; /*mejor sacar el negativo de la potencia*/ 
real Beta = (1 - aa4 * exp (aa5*Time_min)); 
real k0 = 1.78e-02; 
real Ea = -13900; /*mejor sacar el negativo de la potencia*/ 
real ks = k0 * exp (Ea/(8.314 * C_T(c,t))); 
real k = (ks * kdiff)/(ks + kdiff); 
if (XCaO != 0) 
{ 
    *rr = 60 * k * Beta * NSO2;  
} 
else 
{ 
    *rr = 0; 
} 
/*return;*/ 
}

當我跑我的模擬，它apperead以下錯誤：

我也在流利地工作，想做一個動態網格的UDF，所以需要一個用於C++的udf.h頭文件。我從google獲得了一個。但它顯示了許多錯誤的：

我不能告訴，如果上面的代碼是一個解決這個問題，但如果它顯示錯誤，這顯然不是一個問的人一直在尋找。請在發佈之前提高您的回答並進行測試，同時限制您在答案中多次發佈電子郵件地址，它屬於評論部分。 –
