values of the quadrature point data on other cells if the corresponding cells
on the new mesh are assigned to this process after subdividing the new mesh. A
global communication of these data elements is therefore necessary, making the

<h5>Ensuring mesh regularity</h5> At present, the program makes no attempt
$M^n=M^{n,n-1}=M$ and $A^n=A^{n,n-1}=A$. On the other hand, if we had
used different shape functions, then we would have to compute
integrals that contain shape functions defined on two meshes. This is a
-somewhat messy process that we omit here, but that is treated in some
-detail in @ref step_22 "step-22".

Under these conditions (i.e. a mesh that doesn't change), one can optimize the
solution procedure a bit by basically eliminating the solution of the second
In the beginning the Universe was created. This has made a lot of
people very angry and has been widely regarded as a bad move.
