The Rosenbrock solver is the default solver as it is good for stiff sets of equations (most common in DynoChem models) and also has a high order, so will tend to take fewer steps than a lower order solver (e.g. Backwards Euler).

The following solver algorithms are also available for running simulations:

• Backwards Euler
• LSODA.

• Accuracy = 1e-3. Show me more on solver accuracy.
• No. of points = 50 (Dynochem) or 100 (Reaction Lab). Show me more on no. of points.
