This keyword is used if there are pipes to be dimensioned with criteria other than the ones used in global dimensioning, which is described under the keyword *DIAM.
FORMAT:
*LDIM <“ledningsid”, krit1, krit2, LIM, sida>
Where:
“ledningsid”: The name of the pipe to be dimensioned.
krit1: Max. permitted velocity in m/s.
krit2: Maximum permitted gradient in Pa/m.
LIM: The pipe diameter in mm below which the velocity criterion is to
be applied and above which the gradient is to be applied.
sida: Is the same as *, 1 or 2 depending on whether both the supply pipe and
the return pipe, only the supply pipe or only the return pipe is to be dimensioned.
Note that when this keyword is used, the pipes in question are dimensioned using the specified pipe types under the *DIAM keyword. If only velocity is to be used, krit2 and LIM must be equal to 9.9999E+30 or “*”. Similarly, if only the gradient criterion is to be used, krit1 and LIM must be equal to 9.9999E+30 or “*”.
There is no limit on the number of pipes that can be dimensioned.
