parameters['reorder_dofs_serial'] = False

Asked by imranal

I tried looking in the complete programmer's reference what this variable is, but unfortunately could not find any information.

What does the following code imply :

parameters['reorder_dofs_serial'] = False

If False dofs will not be reordered in serial runs. When not reordered
they will follow the UFC numbering, which means for a CG1 space, that
the dofs will follow the vertex numbering. For a MixedSpace all dofs
from the first space come first followed by the second space aso.

Bear in mind that this is not guaranteed - it just happens to be the
case at present when FFC generates the dof map.
