Re: NNULLP command
 
Hi,

This is the line which I am not able to understand:
if (NNULLP(THREAD_STORAGE(t,SV_T_AP))) ap = -C_STORAGE_R(c,t,SV_T_AP);

What does NNULLP and C_STORAGE do? I checked the FLUENT UDF manual but it's still a doubt for me.

Thanks,
Yash

Hi.

Could anyone kindly tell me the meaning of AP in this line:

#define C_T_AP(c,t)C_STORAGE_R(c,t,SV_T_AP)

What is it's use?
