I am trying to simplify an expression and taking the real part only. However Mathematica use ages to run the command (if it is able to do so in the end). The problem is that the expression I am working with is extremely huge (centerElectron, about 400 000 characters).
simplifiedCenterElectron = Simplify[ComplexExpand[Re[centerElectron]]]
Do anyone have any hints as to how I could make Mathematica run this faster? And will it be able to do so in the end for a 400 000 character expression?
