Re: Compilation does not work
Hi
After the compilation fails, Vensim says 'failed to compile the model (does not exist)'.
the other warnings are in the echos of the command file I joined.

Re: Compilation does not work
Hi
I have verified again the paths asked in the batch file. Evenrything is OK and the VsDevCmd.bat file exists.
the only thing that I cannot verify is the '-arch=amd64' at the end of the call. i do not know what it means.
Regards.

Re: old sketch
Hi
Is it possible to switch the sketch to the oldest presentation that was in used some years before and used less place, allowing more place for the model equations?

Hi A better version 6 that adds the calculation of the resting time in the elevator, especially if the starting time of the rest is close to the end of the climbing the elevator. It renames too most of the auxiliaries to initials, which is clearer. It calculates as initial the total time spent, show...

Re: Population Model
the population model is very approximative and does not resist to extreme conditions tests. For example, if the births are set to constant 0 with the synthesim starting at year 1900 and the final time set to 2200. 8 % of the initial population is still in life 200 years later. It comes from the fact...

Re: Population Model
Hi The deaths loop is a balancing loop and the births one is a reinforcing loop. Balancing loops do not necessarily need a goal. If the population is increasing the births are increasing as the deaths do, but births are added and deaths are subtracted to the population and this makes the difference ...
