采用UDF，初始化时错误

liweishihao

用udf设定随温度变化的密度。将解释好的udf导入之后，在初始化时fluent显示错误如下：
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: ()

UDF内容如下：（温度低于320K，密度为常量；高于320K，密度线性变化）
#include "udf.h"
DEFINE_PROPERTY(cell_density, c, t)
{
real mu_lam;
real temp = C_T(c, t);
if (temp<320)
mu_lam = 1223.6;

else
mu_lam = 1223.6*(3.4615-temp/130);
return mu_lam;
}
