Hi,

I recently need to do some numerical simulation by Euler method to solve a PDE.

However, I noticed that there are some errors which are obtained with bigger numerical steps, when applying Euler scheme.

Since my major is not mathematics, I do not know what this phenomenon is called. I have read it somewhere else (from Wikipedia ?), but unfortunately I cannot recall it at all.

Anyone knows the name of this ?

Thank you so much !
