Hi, I'm trying to create a solution for fatigue strength which makes use of the log10 function. I can't seem to get it working with values which have units defined for them. ignoring units also doesn't help for the calculation. Completely removing units does work, but isn't preferred. Does anyone have a workaround or method that works with the use of units?
