void oofem::Quad2PlateSubSoil::computeBmatrixAt ( GaussPoint gp,
FloatMatrix answer,
int  lowerIndx = 1,
int  upperIndx = ALL_STRAINS 
)
protectedvirtual

Computes the geometrical matrix of receiver in given integration point.

The product of this matrix (assembled at given integration point) and element displacement vector is element strain vector. If lowerIndx and upperIndx parameters are specified, answer is formed only for strains within this interval. This will affects the size of answer.

Parameters
gpIntegration point for which answer is computed.
answerGeometric matrix of receiver.
lowerIndxIf specified, answer is formed only for strain with index equal and greater than lowerIndx. This parameter has default value 1 (answer is formed from first strain).
upperIndxIf specified, answer is formed only for strain with index less and equal than upperIndx. This parameter has default value ALL_STRAINS (answer is formed for all strains).

void oofem::Quad2PlateSubSoil::computeGaussPoints ( )
protectedvirtual

Initializes the array of integration rules member variable.

Element can have multiple integration rules for different tasks. For example structural element family class uses this feature to implement transparent support for reduced and selective integration of some strain components. Must be defined by terminator classes.

Returns the interpolation for the specific dof id.

Special elements which uses a mixed interpolation should reimplement this method.

Parameters
idID of the dof for the for the requested interpolation.
Returns
Appropriate interpolation, or NULL if none exists.

IRResultType oofem::Quad2PlateSubSoil::initializeFrom ( InputRecord ir)
virtual

Initializes receiver according to object description stored in input record.

This function is called immediately after creating object using constructor. Input record can be imagined as data record in component database belonging to receiver. Receiver may use value-name extracting functions to extract particular field from record.
