Default unable to determine machine architecture

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,

The following commands may help you.

1. uname -a 2. cat /etc/issue 3. cat /proc/cpuinfo

Set the Env variable FLUENT_ARCH to lnamd64
