\chapter{Frequently Asked Questions}


\begin{finger}
\item Which timestep should I choose to avoid crashes of the model ?
\item In the Martian simulations, why can't I define boundaries each 6 hours as on Earth ?
\item Help ! I get strange assembler errors or ILM errors while compiling !
\item Is it possible to run the model on a specific configuration that is not supported ?
\item Why do I have to define four less rows in the parent domain
when performing nested runs ?
\item I am kind of nostalgic of early/middle Mars. How could I run
mesoscale simulations at low/high obliquity ?
\item Why \ttt{real.exe} is crashing when the model top pressure is
lower than $2$~Pa ?
\item Can I use the two-way nesting ?
\item How can I change smoothing surface properties ?
