Error: received a fatal signal (Segmentation fault).

UDF 代码：

#include "udf.h"

#include <math.h>

DEFINE_MASS_TRANSFER(liq_gas_source, cell, thread, from_index, from_species_index, to_index, to_species_index)

{

real m_lg, K, R;

real YI_SAT = 1.5e-6;

Thread *gas, *liq;

gas = THREAD_SUB_THREAD(thread, from_index);

liq = THREAD_SUB_THREAD(thread, to_index);

m_lg = 0.0;

if((C_YI(cell,liq,1)>YI_SAT)&&(C_VOF(cell,liq)>0.)&&(C_VOF(cell,gas)<=1))

{

R=45.833e-6*sqrt(CURRENT_TIME-30.0)+0.833e-6;

K= 7.38e-9*(1/(R)+1/sqrt(3.14157.38e-9(CURRENT_TIME-30.0)));

m_lg =-1000K(C_YI(cell,liq,1)- YI_SAT);

}

return (m_lg);

}

请问在Fluent里选择的Non-Equilibrium Wall Functions壁面函数，在openFoam中选择哪个壁面函数较为合适呢？
