For the usage of

C_YI(cell,thread,i)

I need to know which species hides behind the integer i!

How can I know this?

[sega]

May this be the list from the GUI:

Materials / Mixture / Properties: Mixture Species / Edit / Selected Species ?

Is there a way to search for a specific species in this list?
Just to make sure I got the right one?

This is an example for printing the species information on the console.
#include "udf.h"
DEFINE_ON_DEMAND(species_list)
{
int i = -1;
char *spe_name;
Domain *d=NULL;
Material *mix_mat=NULL;
d=Get_Domain(1);
mix_mat= mixture_material(d);
mixture_species_loop_i(mix_mat,i)
{
spe_name=MIXTURE_SPECIE_NAME(mix_mat,i);
Message0("species index=%d,species name=%s\n",i,spe_name);
}
}

}

Just great!
Thank you!

How is this related to the topic?

Hi,
I also have to know the numbers for the species, but I don't know how to run this code :-( Can anybody explain how I get this information out of this code? I also tried to copy the code and paste it into the console. I also tried to compile this code, but I don't know how to start it.

cheers

1. Read the manuel about UDF.
2. Save the code as *.c file.
3. In FLUENT go to menu: Define > User-Defined > Functions > Compiled ...
4. Add the c-File (Source File)
5. Click Load
6. FLUENT menu: Define > User-Defined > Execute on demand
7. Choose the function
8. Output appears. Done!

Hi Sega,

thanks a lot. I've already done nr. 1-5, but didn't know how to execute this file. Now it's working fine.

Thanks

Wow!
thanks a lot That was so helpful to me! saved so much of my time!

Btw fluent manual (12.0 version) doesn't list anything about this macros right?? Plz correct me if i'm wrong!
where u got the info on using these macros????

[Abhya]

Hey I found another simple way to access the species index using macro - SV_SpeciesIndex("species_name")
species_name should exactly be the name we see in the Models-> Species transport panel!

Refer the following code for example :

#include "udf.h"
DEFINE_ON_DEMAND(M_species_list)
{
int i;

i = SV_SpeciesIndex("h2o");

Message("species index=%d,species name=h2o\n",i);

}

[gearboy]

Great job!

M_species_list:
0 .local.varargs
0 .local.end
0 save
.local.int i (r1)
1 push.int 0
3 save
4 push.string [5] Licl
7 call SV_SpeciesIndex (-1)
9 sto.int i (r1)
11 pop.int
12 save
13 push.string [36] species index=%d,species name=Licl

20 ld.int i (r1)
22 call CX_Message (-1)
24 pop.int
25 restore
26 ret.v
How can i know wht is the i for licl. plz hlp

I executed the code, it gets compiled, and then it does not print anything for me Can anybody guess what might be the problem?

[AlexanderZ]

how did you run the code?
