I am interested in running axisymmetric pipe flow problems including heat transfer.
Can anyone provide me with .cfg & .su2 files for a simple example to get started?

Your help is much appreciated.

Kind regards, Tim

Hi,
I haven't found the option to select an axisymmetric boundary condition.

Can someone please direct me to the documentation for this?

Kind regards, Tim

Hi Tim,

You can perform an axisymmetric simulation by adding the following two lines to your config file:

AXISYMMETRIC= YES
SOUR_NUM_METHOD_FLOW= PIECEWISE_CONSTANT

Hope this helps,
Aniket

Hi,

Can you share some testcases for axisymmetric flow in SU2 ?

Aniket,

I'm not sure the second option is correct in the latest versions (4.1), I tried it and got the following error.

"SOUR_NUM_METHOD_FLOW: invalid option name. Check current SU2 options in config_template.cfg."

I just use the first option and use a symmetry boundary condition for the axis. Even then I'm a little dubious of the result as it outputs positive values of lift whereas if the simulation was truly axisymmetric the lift should be equal to 0.

Hey Aniket,
I get the same error as Mike for "SOUR_NUM_METHOD_FLOW".
However, the first option (AXISYMMETRIC = YES) works only for compressible for me and gives segmentation fault for incompressible.
How can I fix this?

Thanks,
Ankita

I have the same doubt. There should not be any lift for axisymmetric case.
