I am doing some biasing using the weight window (with command WW-FACTOr). But I have done a test without biasing and I get the same result! Why?
Check that you have a
WW-THRESh card in your input. It is compulsory when using
WW-FACTOr, otherwise the two energy thresholds are set equal to zero, and it is as if the weight window was not there.
