Hi,

I am trying to run fluent 16.1 in batch mode using Linux openSUSE and I am using the following command:
fluent161 3ddp -g -i fluent.jou

My journal (fluent.jou) contains:
file/read-case-data Test.cas
solve/initialize initialize
solve/iterate 20
file/write-case-data Test.dat
exit
yes

When I`m trying to run fluent this way, everything is fine.

Now I want to use a UDF file.
When I try to run fluent with the GUI everything is fine. I can compile and hook my UDF and Fluent calculates the solution.
But when I try the same case (with the compiled and loaded UDF) in batch mode, Fluent doesn`t calculate the solution.

The following message appears:
/usr/ansys_inc/v161/fluent/fluent16.1.0/lnamd64/3ddp/fluent.16.1.0: symbol lookup error: libudf/lnamd64/3ddp/libudf.so: undefined symbol: F_PART


Does anyone have a solution for this?


Thanks

hi tobi

have you tried including a command after the one that opens the case & data file, that will load the UDF library ?

Hi,
i `m sorry for my late answer!
But now I have the solution to my problem.
The problem was that I run fluent in parallel,when I was trying out the UDF.

But on Batch Mode I run fluent serial. But there is a difference in the wording of the UDF library in parallel or serial operation.
In parallel, there are two folders in the path libudf/lnamd64/: 3ddp_host and 3ddp_node
but in serial there is just one folder: 3ddp. Therfore fluent could not find the folder
3ddp in serial use in batch mode.

In parallel, it worked then perfectly.

Greetings
