[TRNSYS-users] equation

[Hermann Schranzhofer]

Dear Marcus and Roman,

 

it is even simpler if you use the FORTRAN notation. Thus the equation in TRNSYS can be written in x**(1/2)

 

Best regards,

Hermann.

The square root of x is equal to x to the ½ power, so you could use the natural logarithm and its inverse. In a TRNSYS equation: exp(1/2*ln(x))

Trnsys users,
 
I had some problem with using the equation in Trnsys. 
 
I need to put "sqrt" inside the equation but i don't find the special operator to do that ?
 
Can i have some help from you ?
 
Thanks a lot!
Justine.R
