right, it is distributed as dynamic link library (DLL) in Windows available in this forums and just simple copy in the same directory of CalculiX solver to ready to use. I successfully test of large material models of plasticity and damage, it’s fast and stable to beat compete with another commercial solver to fulfill CalculiX material libraries internal solver limitation.
