Just to make this all more visible, the links to MOLEC2_03.pdf
are broken on the following page:
As I had written before, other tools link to that or the previous version 2.02 of the molecules and—since they have been published with permission as pdf
—they should be made available on systemdynamics.org
once more, shouldn’t they?
On the other hand I do note, that the molecules shown at sdmolecules.org
are now built using isee system’s Stella (they used to be built with Vensim), that the introduction to System Dynamics is given by a webinar using Stella, and that the molecules are now offered as Stella models for download.
I hope, that there is not too much of vested interest at play here, when you, Bob, propose to only link to the sdmolecules.org
page in the future as a member of the SDS policy council? I would assume, that linking both, the pdf and the website, will be a fair compromise.
This clear notion of vendor interests in the SDS has been one of the main reasons for me, to offer a library as open source using an open source modeling language with proporietary as well as open source software choices available.
Happy holidays,
