OpenersNotesSection(Spacer1)Details

This message is generated when the value of the (RefLink[MaxStepSize, paclet:ref/MaxStepSize]) option leads to an excessive number of steps.

(RefLink[Off, paclet:ref/Off])[message] switches off the message; (RefLink[On, paclet:ref/On])[message] switches it on. For example: (RefLink[Off, paclet:ref/Off])[(RefLink[NDSolve, paclet:ref/NDSolve])::msti].

An error occurs because of the excessively small value of the (RefLink[MaxStepSize, paclet:ref/MaxStepSize]) option:

NDSolve[{D[u[x,t],t] == D[u[x,t],x,x],u[x,0] == Exp[-100 x^2], u[-1,t] == u[1,t]},u,{x,-1,1},{t,2}, Method->{"MethodOfLines", "SpatialDiscretization"->{"TensorProductGrid",MaxStepSize->2^-32}}]
