I am using Ansys 18.2 (Ansys IC Engine (fluent)) in CentOS 7. I am adding valve.prof (a profile file) before opening the Ansys Design Modeler. However, during the decomposition step I get this error message:

All lift valves are zero. Check valve lift profile format. TIP: Try using dos2unix command to convert the file to unix format.

I've only worked on Windows before; what does this mean? How do I use dos2unix here?

The error message asks you to run dos2unix on (presumably) the valve.conf file since it may be a DOS text file. Unix text files have an ever so slightly different format from DOS text files and many programs that expects Unix formatted text files have issues reading DOS text files properly.

To install dos2unix on CentOS, if it is not already installed, open a terminal window and type the command

sudo yum install dos2unix

(this assumes that you are allowed to use the sudo command to execute things as the root administrative superuser).

Then, to hopefully fix the error, you would run the command

dos2unix valve.conf

(assuming that the file is located in the current directory).
