Possible Issues Encountered in NetSim when using incorrect settings:
- Error pop-up in NetSim GUI.
- An unknown exception error occurs with the message "The input string '0.8' was not in a correct format."
- This is due to Windows regional settings set to any other language, the decimal separator for some countries is comma instead of a dot and list separator is dot instead of comma.
- An unknown exception error occurs with the message "The input string '0.8' was not in a correct format."
- Cannot simulate few of NetSim built-in examples and experiment.
- For Example: Open the Pure Aloha experiment with 10 Nodes and run the simulation.
- The simulation does not progress from 0% as shown in the screenshot above because of the Configuration.netsim contains comma, dot and hyphen which are treated as different formats in different countries.
- For Example: Open the Pure Aloha experiment with 10 Nodes and run the simulation.
