Hello guys,


I have a quick question.
Is there a reason of why i can't use "c-structured" variables on my interpreted UDF codes? I am using a 4core parallel fluent. Interpreting, then, fluent is giving the error



' Error: ~/*.c line 43: declaration: invalid opcode pop.char '



as you can see in the attachment. In the line 43 I have the c-structured variable.

try to compile your code instead of interpret

Or show a little of your code, especially around line 43.


For you, "c-structured variable" seems like a normal term, but I don't understand what you mean with this, and Google does not help. Don't describe your code if you want help with it, just show it!

Thank you for your fast answer.


The point is that I always compiled my code on a serial fluent and now I want to get the analysis faster using a parallel fluent.

I saw 2 solution:

1) Interpret the code;
2) Compile it with something like this

http://www.afs.enea.it/project/neptu...df/node230.htm
but it seems a bit complicated for me, so I wanted to interpret.


On the attachment you can see an example of a C-structured.


So I want to interpret it, but it shows that error.

[AlexanderZ]

you've put a picture of your code here.

the thing is you don;t have to if it is too complicated for you

best regards

I'm just asking what is the problem with that structure in a interpreted code. Is there a solution? If you try to compile just a simple code with a variable like that fluent is not working or at least on my computer is not working.

Thank you and Regards

If you interpret c-code, not everything will work. And, apparently, structs don't work.



The solution is to compile.


If you want to do a parallel calculation, you might have to adjust your code a bit.
* Sometimes you have to change nothing.
* Usually you have to add just a few #if lines.
* Sometimes you have to change more, like in the example you gave.


You said that if you try to compile just a simple code with a variable like that fluent is not working: this just means that you made a mistake in your code. You have given us not enough information to find out what the mistake is.

Okay then, I will try to compile and insert #if statements.
Thank you for your quick answer.


Regards.
