Does any one knows the difference between the alloy and composites ?

For example If we add 30wt.% Cr, 5wt.% tungsten (W), 2wt% Ni and rest is Cobalt. so after casting what is called as : 1) Is it an alloy..? or 2) is it an metal matrix alloy composite..?

fatal error

When I tried to energy minimization my system, I got fatal error as below. Fatal error: Atomtype opls_116 not found Although I've already added this line: ; include water #include "oplsaa.ff/spc.itp" to [molecultype] directive in my topology.
