Ansys 57 on 64-bit Debian 12 Bookworm

1. copy old installation tree

2. try it it runs:

 ~$ /ansys_inc/ansys57/bin/xansys57
bash: /ansys_inc/ansys57/bin/xansys57: cannot execute: required file not found

or:

 ~$ LM_LICENSE_FILE=1057@server /ansys_inc/ansys57/bin/ansys57 < inputfile.inp

If this works, change the variable definition: setenv ANSYSLIC_DIR /ansys_inc/ansys57
in /ansys_inc/ansys57/bin/anscript57.ini
and create the license file

echo SERVER=1057@server > /ansys_inc/ansys57/ansyslmd.ini 

3. add missing binaries

# apt install ncompress tcsh
# dpkg --add-architecture i386
# apt-get update
# apt install libc6-i386

ldd command lists missing libraries:

# ldd /ansys_inc/ansys57/bin/linuxia32/xans.e57

....

# apt-get install   libxi6:i386
# apt-get install   libxt6:i386
# apt-get install   libxpm4:i386
# dpkg -L  libxpm4:i386
# ln -s /usr/lib/i386-linux-gnu/libXpm.so.4.11.0 /usr/lib/i386-linux-gnu/libXp.so.6

# The Motif library libXm.so.2 is included in the original tree in a rpm file: extract libraries from

/ansys_inc/ansys57/syslib/OPENMOTIF/openmotif-2.1.30-2_ICS.i386.rpm
/ansys_inc/ansys57/syslib/MESA/Mesa-3.2-1rh61.i386.rpm

into /ansys_inc/ansys57/syslib/linuxia32 folder and create symlink:

cd /ansys_inc/ansys57/syslib/linuxia32
ln -s libXm.so.2.1 libXm.so.2
