JSim uses this file to store models that can be edited and compiled in the application. A model may contain one or more MML model definitions.
JSim can manipulate model parameters, run simulations, and display the resulting data as graphs. The .jsml file provides the model input for these operations.
The file is associated with the Windows version of JSim. It is best handled within JSim, which understands the model's structure and syntax.
Open the .jsml file in JSim on Microsoft Windows. Use JSim's Open command if double-clicking the file does not launch the application.
Because the file contains a JSim model, other text editors or modeling programs may not interpret it correctly.
Open the .jsml file in JSim to edit the model and save it using the formats supported by the application.
If the goal is to reuse simulation results rather than the model itself, run the model in JSim and export or copy the resulting data using JSim's available result-handling features.
