Gives a list of location arrays that will be assembled.

This should only be used to construct zero structure in sparse matrices. The rows and columns location arrays returned in tuples (stored in vector), allowing to efficiently assemble and allocate off-diagonal blocks. The nonzero entries are assembled and allocated for entries at (rows[i], cols[i]) positions.

Parameters
rowsList of location arrays for r_s.
colsList of location arrays for c_s.
typeType of matrix to assemble.
r_sRow numbering scheme.
c_sColumn numbering scheme.

int oofem::MixedGradientPressureWeakPeriodic::giveNumberOfInternalDofManagers ( )

Returns the number of internal DOF managers (=2).

This boundary condition stores its own DOF managers, one for tractions and one for $ d_{\mathrm{vol}} $ which is a single DOF for the volumetric gradient.

Initializes receiver according to object description stored in input record.

The input record contains two fields;

  • devGradient #columns { d_11 d_22 ... d_21 ... } (required)
