8. If you halve the discretisation of your model, i.e., from ∆x = ∆y = 100 m to ∆x = ∆y = 50 m, what will happen to the model truncation error?

Question

8.	If you halve the discretisation of your model, i.e., from ∆x = ∆y = 100 m to ∆x = ∆y = 50 m, what will happen to the model truncation error?

Answer

Truncation error decreases by a factor of 2 (halves)

Answer

Truncation error decreases by more than a factor of 2

Answer

Truncation error increases by a factor of 2 (doubles)

Answer

Truncation error increases by less than a factor of 2
