Default unable to determine machine architecture
Posts: n/a
Dear All,

I am running Fluent on 64-bit LINUX machine. I try to run UDF's from Fluent tutorials by using text user interface (TUI). At UDF Manual (5.3 Compile a UDF Using the TUI page 5-12) step 6. identify the architecture name of the machine that you are running from. I run the FLUENT utility program fluent_arch at the command line of a UNIX shell.

ERROR message: usera@lptsv743:~>fluent_arch /Fluent.Inc/bin/fluent_arch: Unable to determine machine architecture. Set the environment variable FLUENT_ARCH and try again.

The thing is I can run simulations on workstation without problem but I can't use/compile UDFs. I would like to know if the problem is due to wrong installation of some components. Can you please advise something on that?

with kind regards,
