At August, I upgraded my UBUNTU 16.04 to 18.04. This version is great.
However, I met a problem when starting ICEMCFD 18.0 and 19.0.
I check the start script file of icemcfd at “ansys_inc/v191/icemcfd/linux64_amd/bin”. There are two solutions:

Solution 1

If you don’t want to change the icemcfd start script, just run the following command:

icemcfd -log tmp.log

-log is a icemcfd argument, tmp.log is the log file generated at your pwd.

Solution 2

If you use other argument when you start icemcfd, the following solution may be not very good. (I don’t use arguments when start icemcfd, so it works well for me) First- cd to your icemcfd bin dir:

cd /usr/ansys_inc/v191/icemcfd/linux64_amd/bin

Then: edit the icemcfd shell script by any text editor you want, here we use gvim:

gvim icemcfd

change line 607: from eval "$ICEM_ACN/bin/med" "$args" to "$ICEM_ACN/bin/med" $args or $ICEM_ACN/bin/med
