I am trying to enter the following equation:



As the formula definition in the dependency type of a boundary condition.


However it states that this is the wrong number format.


I suspect it is due to the ABS call out (or absolute value calculation)


Does anyone know flow simulation can calculate the absolute value?


The purpose to the equation is to create a half sine wave or in simpler terms turn on and off the flow of CO2 in my case.
