Keychain Validator
Keychain validator compares the keychains in the .cfg file with valid nanoFluidX keychains, when activated.
The keyword chain is formatted as key1.key2 for two level and
key1.key2(#).key3 for three level keyword chains. Here, key1 is
the highest level keyword. For example “phases'', key2 is the second level keyword,
for example “phase'', key3 is the third level keyword, for example “type''. In three
level keyword chains, the second level key is accompanied by a number in parentheses
pointing to the order in second level keyword list. Keychain validator is context
sensitive, for example phases.phase(2).rho_compr is printed as a
warning for a non-FLUID phase 2.
Unrecognized keyword chain: key1.key2.
Unrecognized keyword chain: key1.key2(#).key3.
Receiving a warning may not necessarily point to a problem. Keychain validator is activated by setting the value of valKeychains keyword in simulationParameters to true. It is not active by default.
