Re: CalculiX- 2.16 - testers needed

What's the best way to get arpack for CentOS? Looks like it's not in the main repository.
As root, just by typing "yum install arpack.x86_64 arpack-devel.x86_64"

Hi Very interesting If I were you I would have a look to Pr Kraska website ( https://github.com/mkraska/CalculiX-Examples/ ) to maybe find a usefull script to get forces passing through all bolts.
