@rdeits My complete code reads the value for “nelementnodes” from an input text file. The input text file can have a different value for nelementnodes from run to run. Will this approach (value type argument) still work as intended?
See Performance Tips · The Julia Language.
As long as you create your types outside the function that do the core computation, you are fine.

Sure! As long as your code looks something like:
function main(filename)
nelementnodes = read_data_from_file(filename)
long_running_computation(Val(nelementnodes))
end
then you should be fine. There’s a computational cost to constructing a Val from a run-time value, but that cost is only a few hundred nanoseconds and you’re only paying it once per call of long_running_computation, so that should be completely negligible.
