blockMesh error

Recently, I met the problem when I ran blockMesh

word::stripInvalid() called for word hostname localhost-01
    For debug level (= 2) > 1 this is considered fatal

the problem may come from postfix mail service. when checked your postfix, it output

valid_hostname: invalid character 32(decimal): localhost-01
postfix: fatal: unable to use my own hostname localhost-01

The reason was that there’s a space, which value is 32 in ASCII in decimal. The problem was caused by postfix.

the solution was to edit /etc/postfix/ Uncomment the line with your hostname like this


Without any special character or space before or after the hostname “localhost-01″.

Then it was success without error.

sudo systemctl restart postfix.service

Then restart the computer. It works.

it may not work every time. I cannot reproduce the error.    Send article as PDF
