Questions:


I am creating tank tables using ullages with the stop command :
    
     tc (sw*.*) ull: 0 0.5 ... 30 /stop:empty /fsm / vol /we /fsm /noload
    
Is there a way to give the exact ullage when the tank is at zero volume.  I
noitced that the stop command just gives the next full increment (in this
case, multipes of 0.5m) to correspond to zero volume.

Answer:

You could do it on an individual tank basis (where you issue a separate
TC command for each tank) by making use of the HEIGHT variable and the
TOP/BOTTOM feature of the REFPT command to calculate the maximum ullage,
setting the value to a user variable which you could then place into the TC
command.
