Active Initial test model?

[tonyvsuk]

I'm in the process of running the test models through Vensim, but hit a problem.

I'm referring to
https://github.com/SDXorg/test-models/tree/master/tests/active_initial

The development version of Vensim reads the XMILE version fine, but the results are different from the Vensim format model. I cannot see in the XMILE version where the call to active initial is actually made.

Am I misreading things?

Tony.

PS, if this is not the correct place to ask questions, feel free to point me in the right direction.

Hey Tony,

I think your reading is correct, that the vensim->xmile translator that generated this model isn't correct. I would expect to see the active initial here.
@wasbridge - do you have a list of which of the tests pass the whole mdl->xmile->stella->timeseries output pathway?

I would expect to see an <init_eqn> tag containing the value 45.

Here is an example generated directly by Stella

<aux name="X"> <eqn>TIME + RANDOM(0, TIME, 1234)</eqn> <init_eqn>77</init_eqn> </aux>

[tonyvsuk]

I cannot see <init_eqn> in the XMILE spec. I can probably implement it though, but where does it fit into the XML tree? You can already of multiple equations for various elements, so how do you tie <init_eqn> to the correct tag?

[wasbridge]

It always goes next to the <eqn> tag (at least how we've implemented it).

Here are all of the examples (scalar, A2A (apply to all) and Non A2A)

<aux name="X"> <eqn>TIME + RANDOM(0, TIME, 1234)</eqn> <init_eqn>77</init_eqn> </aux> <aux name="A2A array"> <dimensions> <dim name="Dimension"/> </dimensions> <eqn>RANDOM(0, TIME, 1234)</eqn> <init_eqn>66</init_eqn> </aux> <aux name="Non A2A array"> <dimensions> <dim name="Dimension"/> </dimensions> <element subscript="1"> <eqn>RANDOM(0, TIME, 1234)</eqn> <init_eqn>1</init_eqn> </element> <element subscript="2"> <eqn>RANDOM(0, TIME, 1234)</eqn> <init_eqn>2</init_eqn> </element> <element subscript="3"> <eqn>RANDOM(0, TIME, 1234)</eqn> <init_eqn>3</init_eqn> </element> <element subscript="4"> <eqn>RANDOM(0, TIME, 1234)</eqn> <init_eqn>4</init_eqn> </element> </aux>
