Solution(s) for
evaluation
The properties Blocksize and Const are described in assemble.
The property Ext determines how far the extrapolation reaches. A positive value Ext
means that for points outside the mesh, the evaluation is carried out by extrapolation
from the nearest mesh element, provided that the distance to the mesh element is
at most ext times the element diameter, roughly. Other (more distant) points
outside the mesh give the value NaN in the value matrices vi.
The property Matherr is described in femsolver.
If the property U does not specify the mesh case number, it is given by the property
Mcase. The default is the mesh case that has the greatest number of degrees of
freedom.
