Usage of control rules

Hi,

This is about the control rules.

I am trying to simulate a network with the help of control rules.

Total simulation period is 2 hrs and 30 minutes, however, I'm running the simulation part by part. Eg 0 to 15 minutes, 15 to 30 minutes, 30 to 45 minutes and so on.

I wanted to input the state of the storage tanks, nodes, conduits of the previous simulation to the next simulation. 

As an example, the depth of the tank1 at 15 minutes from 0 to 15 minutes simulation should be input to the 15 to 30 minutes simulation. This is to keep the mass balance.

 

I think the depths can be input using the following control rule. But, I am not sure. If these are incorrect, please let me know the correct rules too.

 

IF SIMULATION CLOCKTIME = 00:15:00

THEN Tank1 DEPTH = 0.4

AND Tank2 DEPTH = 0.5

AND Node1 DEPTH = 0.3

AND Conduit1 DEPTH = 0.15

 

However, I wanted to input the pollutant concentration levels at these locations.

There are 5 different pollution constituents and if the above control rules are correct, please reveal me the control rules to feed the pollution concentration levels.

 

The second question is;

What will be the maximum number of control rules that I can insert to the simulation. I  mean is there a maximum number of control rules that we can use?

 

Thanks a lot.

  • Hi Robert,

    Thanks a lot for letting me know.

    How should I set the water depths at nodes for a given time?

    I tried the following, but it gives me an error report with "invalid keyword NODE at line ..."

     

    RULE R1a

    IF SIMULATION CLOCKTIME = 00:15:00

    THEN NODE TANK1 DEPTH = 0.4

     

    Thanks again.

     

     

  • Hi, You cannot set the concentrations using the control rules.
