Typically, tasks are in an array dimension, so you want to be sure that all the needed elements are active in the Subscript Control.

If you're on a Surface, can we assume Win 10?

Fixed, I think. Here's the result.

I think it's a bug in the iteration. Should be a quick fix. Sorry.

Sorry, not on one view. However, you could copy/paste the entire sketch (using the Picture option). That would give you a second view with independent depth settings. So, in a sense you could have unlimited depth by creating multiple views. The only drawback would be the requirement for some coordin...

I understand exactly what you're seeking, and it should work, but currently doesn't. I'll post an example and a new build as soon as it's fixed. In the general case, where you have many WidgetIDs with different Type attributes, and you want the lookup to vary by Type rather than Widget, you'd create...

After my change, this system is basically an aging chain or Nth order delay, with behavior like this: However, there's no inflow to the system, so the equilibrium values will all be 0 eventually.

I think you need to get clear on the flow structure here and use the diagramming to full advantage to capture what's going on physically. Simplifying a bit, you have: BOD.png This shows "BOD rate" flowing into C1, but in fact BOD rate is negative, so it's really an outflow. In addition, yo...

The terms in the equation should be normalized by reference values of output, capital and labor, like: Y/Y0 = A * (K/K0)^alpha * (L/L0)^(1-alpha) so Y = A * Y0 * (K/K0)^alpha * (L/L0)^(1-alpha) Then all the bases of the exponents will be dimensionless, and it's typically easier to initialize the fun...

I see two kinds of errors here: 1. "1000" in this context is not a dimensionless number, it's a scale factor for the production target. It needs to be made into an explicit variable with units of tons to match the left side. *********************************************** Error in units fo...

Just use EXP( RANDOM NORMAL() ), where the parameters of the normal distribution are the geometric mean and standard deviation of the lognormal.

Not at all - this one's an easy fix, but it's not obvious!

Yes, you can do this. As an example, you might have two kinds of entity: Person, identified by a PersonID attribute Relationship, identified by the IDs of two Persons Then you just need to specify the network as a table of relationships that exist among the persons. For now, you'd either have to imp...

My guess is that the model builder linked the Excel file as: someVar = GET XLS DATA( '?datafile', ... ) The ? triggers a prompt for the file location, which subsequently may be stored as an absolute path. Later, on your machine, if the path is invalid the ? will trigger a new search. You probably ju...

I haven't had a chance to look at the model, but here's what that message probably means: (a) Somewhere (probably your new "group" entitytype) you have a Reference that points to Cohort entities. If you open the inspector for the new entitytype, and switch to the references tab, you'll fin...

It looks like there's a bug that prevents reading the lookups from the initialization data - I've put in a ticket for that.

I can see the model, but the CHD diagnosis test model1.xlsx file is missing from the archive.

Just to be clear: you want to automate providing a different lookup shape for each entity, via the input data?

Forgot to mention it here, but the (now not so) recent release fixes this.

I thought it might be something like that. My guess is that the periods in the file path are fooling our code that appends the .vdf extension when needed. If the path were "2016-05-11 v1-1-2\ABC.vdf" (dashes instead of periods), it would probably work too. We'll fix it. Thanks for experime...

This is odd - I routinely use short run names; in the model currently open, I have "noK" and "v9" and both work fine. I just tried "ABC" and that works too. Is this Mac or Win, or the x64 version? The engine opens a .vdf for writing when Synthesim starts up, so the erro...

I think the basic problem here is that this is not conceptually a simultaneous situation. "Extraction Rate(Tpy)"=SIMULTANEOUS(IF THEN ELSE(Production Phase=1,0,IF THEN ELSE( "Mineable Reserves(Tons)">("Tons of Ore Mining Rate(Tpy)" +"Tons of Stockpile Mined(Tpy)&qu...

Going further, and assuming that mineable reserves are large, "EXTRACTION RATE(Tpy)"= "TONS OF ORE MINING RATE(Tpy)"+"TONS OF STOCKPILE(Tpy)"+"TONS OF WASTE MINING RATE(Tpy)"+"Expansion Capacity Planning Rate(Tpy)" The first three items on the right ...

If you forget about the simultaneity and eliminate some conditions, the first equation simplifies to: "EXTRACTION RATE(Tpy)"=MIN( MINEABLE RESERVES*"1/year" , "TONS OF ORE MINING RATE(Tpy)"+"TONS OF STOCKPILE(Tpy)"+"TONS OF WASTE MINING RATE(Tpy)"+&q...

A diagram would help, too. It's not obvious why this should involve a simultaneity in the first place.

Can you post the model, or a submodel that illustrates the problem?

What exactly do you mean by "got no results"? Does the simulation generate a dataset? Does it have values for other variables? Are you using a savelist?
