A little more detail. I am trying to create a simulation of a series of batch jobs that will run nightly. some jobs will be scheduled for a specific time; others will be dependency driven (1 or more dependencies). The goal is for the simulation to (a) identify the critical path of the jobs, (b) the duration for each job and (c) the duration for all jobs.
Here is what I have done thus far:
(1) Created a <<constraintBlock>> JobConstraint (in the Library/ConstraintBlocks' package with the following properties:
(a) startTime
(b) volume
(c) throughputPerSec
(d) duration
(e) endTime
(2) Added a formula to compute 'duration' and 'endTime'
duration=volume/throughput
endTime = startTime + duration;
(3) Created a 'BlockDefinition' diagram
Created a constraintBlock job1
Created a parametric diagram for jobs 1 with a property of JobConstraint
Created a properties to define input and output values.
Run a simulation outputting the simulation

I have created a <<Block>> with a property for volume and throughput and set default values to these properties. I tried dropping the block onto the parametric diagram and connecting the block's property to the job1.property (ex. BlockA.volume --> job1.volume). If I run simuation, the default value of BlockA.volume is not passed into the contraint block. I have the option to set a value for BlockA.volume in the simulation window and it still doesn't work. Has anyone got this to work?
