[TRNSYS-users] equation solver problem

Federica,

   The division by zero probably occurs before the values have been read 
(and outputted) by Type9. Try the following:

A/(MAX(0.0001,B)

   Of course this will run into problems if the values of B can be 
either positive or negative)

kind regards,

  David
