Thanks a lot Sir,

That will work, I guess.

But there is 1 more issue. The example which is given in pdf contain only 1 wall (surface).

In my case its a fluid flow inside a metal (thick cylinder) pipe. So how many wall conditions will be made??

Should it be 3:

1 for fluid flowing inside

1-1 each for metal pipe inside and outside surface????

Well, I have carried the whole process in the above mentioned manner (in pdf.) Its showing following error message. (as shown in attached pic)

Components include:

-a solid pipe (half of steel and other half of rubber)

-fluid flowing inside

-ambient air outside

now I have made 2 walls, one for outer (including outer surface elements of steel pipe and rubber pipe and inner surface element of ambient air)

- another for inner (including inner surface element of steel pipe and rubber and outer surface element of fluid flowing outside)

Is it correct way to do it????

where is the mistake.. pls let me know??

Thank You

hello tanuj,

can you please tell me how you created those surfaces or how you named them as inlet and outlet etc.

This document might help. 

@ Ydigit, 

Thank you very much sir.

@ Ydigit, 

I am not able to organize names to the surfaces in my geometry. 

You may be better off contacting your local Altair support team in India.
