Limitations

 

There are some limitations to running a model in a browser.

 

 -        All data and constants must be contained within the model. At present, Vensim WASM models cannot load external data or constants.

 -        At present, only the active model view is published. Anything more advanced is outside the scope of what can be done automatically, but you can use the WASM file and API to create your own web-interface.

 

 

Common problems

 

I do not see a index.html file in the list of output files.

 -        Make sure you are using the new GUI (Tools->Switch to new sketch).

 

I've opened the index.html file in a browser, but the graphs do not update.

 -        You need to open index.html from a web server due to security restrictions, opening the file from your local machine will not work. For testing, there is a Python script that will run a webserver locally.
