Mass & Heat Transfer

sheintz · April 16, 2010, 06:08

Hi everybody ^^

I'm using StarCD 3.26 for the simulation of a spray.

I would like to use the mass transfer subroutine (and the heat transfer subroutine) but when I launch the calculation I have one error :

***ERROR *** Compilation error in user file "ufile/conduc.f"

Before I do with this mass (heat) transfer subroutine I din#t have this error, what do I have to do in the conduc-file ?

Thank you in advance
Best regards

Simon

I have found the solution :
I had to remove the subroutine files (conduc.f , specht.f , viscos.f , ...).
So easy !
I hope it can help someone else.

Hello simon
well i'm Samy and i'm trying to finish my simulation using STARCD 4 well i'm done with the geometry i built it with Star design and i added boundaries condition and i did the running even in the pro star but the problem is:
btw i'm simulating flow in a concentric tube (heat exchanger) you know and interior tuve and another anulus, well the probleme is i dont have a temperature variation in the two channels , so i think i have to use subroutines and i dont master the porous media stuffs, because i have to add on the annulus channel a porous media like chicanes and so, so if you can help me with that it will be great and if you can exchange mails to discuss on it , it will be very nice

thank you
Samy
