Subject: Re: ANSYS License Manager - core file

I do John's method. The bit bucket option below will keep the file from
filling up the disk, but the Ansys program will still take the time to
write all the bits to the "bit-bucket". This soft link method could be
useful if Ansys ever wrote a core file without promptly dying after
writing it. (Like write the core file and then exit normally or be ready
for the mext interactive command...) Does that ever happen?
