Modelling the movement of different amounts soil

Hi There,

I am currently trying to create a model for my undergraduate thesis and it involves measuring the efficiency of soil moved by different machines.

I have assigned volumes to items through labels but have come to a road block.

I have a processor that processes a certain volume and then places that volume block into a queue acting as a stockpile. I then need another processor to pull a different volume from that stockpile and I do not know a way of drawing that volume from the already created set volume blocks.

Is there anyway of creating a running total of volume in a queue and draw from that volume as needed?

Thanks for the help

Yes, there is by SQL. But that is not an optimized pull. You have to find a strategy, from which items do you summarize the label values to process next in the processor.

The SQL clause is SUM(from a column) with the combination of chapter “Advanced Query Techniques“.

Thanks for the reply.

I have found my way around it at the moment by converting to a fluid and then back into a solid. Not the most efficient way probably.

Will have a look at SQL

Cheers
