求助：fluent UDF中M_keCmu 是什么
fluent UDF中M_keCmu 是什么 用双流体模型进行稠密气固射流的计算，想对颗粒相的Turbulent viscosity进行修改，使其大小等于气相的Turbulent viscosity乘以颗粒相的密度，我写的UDF如下：#include "udf.h"
DEFINE_TURBULENT_VISCOSITY(mu_s, c, t)
{
Domain *domain;
domain=Get_Domain(2);
Thread *tm=lookup_thread_by_id(domain,2);
real mu_t;
mu_t = M_keCmu*C_R(c,t)/C_R(c,tm)*C_K(c,tm)*C_K(c,tm)/C_D(c,tm);
return mu_t;
}
报错为：

请问怎么解决，或者在计算颗粒相时怎样用UDF调用气相的turbulent viscosity？
