- For some cases (for instance involving solvent flow) the reasoning for
only adding the pressure derivatives seems to fail. As getting the
sparsity pattern is non-trivial, in terms of work, the full sparsity
pattern is only added when specified by the parameter
"require_full_sparsity_pattern"
- For solvent runs "require_full_sparsity_pattern" defaults to true for
all other runs the default is to only extract the sparsity pattern from
the pressure derivatives.
