Error messages

Input errors

While different nodes have different errors, all nodes (except plots) have input errors/warnings.

Nodes may display an error or a warning icon in the top right corner:



Hovering over the icon will display a diagostic message.

Errors are critical and indicate that the node is unable to calculate its outputs, and the simulation is not runnable.

Warnings are non-critical and indicate possible oversights that may lead to surprising behaviour.

Expression errors

Nodes that allow writing a math-expression have errors looking like "parse error matching struct...". These errors indicate an invalid expression. For a reference of allowed Expressions, see the Expressions-page.
