[TRNSYS-users] Dividing by Zero

[Flynn Ciaran]

Hei Amir,

You can work around this by making a separate equation for the denominator.

For example, set an equation for your denominator (assuming it is always positive) as: If denominator = 0, set "new_denominator" = (-1)
Then link this to your existing equation as: GT(new_denominator,0)*(numerator/new_denominator).
This way if your equation is negative you'll know that you had a division by zero...

Regards,
Ciarán

Dear Users

I am facing a problem where whenever I insert an equation and divide by something, it receive an error that I am dividing by zero.

I made sure that all initial conditions are not zero and I even plotted the value of the variable and it does not equal zero.

I even put a condition that the division only occur if the denominator is >0 but still the same.

Does anyone know what's causing this?

Thank you
