运行网上一个流体程序，但为啥对话框说它11行有没被定义的量，有没有大神帮忙看看....
这是一个自定义材料的粘度程序如下，也许对你有帮助。在记事本中编辑的，另存为"visosity1.c"
#include "udf.h"
DEFINE_PROPERTY(cell_viscosity,cell, thread)
{
real mu_lam;
real trial;
rate=CELL_STRAIN_RATE_MAG(cell, thread);
real temp=C_T(cell, thread);
mu_lam=1.e12;
{
if(rate>1.0e-4 && rate<1.e5)
trial=12830000./rate*log(pow((rate*exp(17440.46/temp)/1.535146e8),0.2817)+pow((1.+pow((rate*exp(17440.46/temp)/1.535146e8),0.5634)),0.5));
else if (rate>=1.e5)

上面的应该都是英文不知道咋回事全变中文了
