getSolution()

void LocalIntegral::getSolution ( size_t  nsd, size_t  nen, Matrix *  u = nullptr, Matrix *  v = nullptr, Matrix *  a = nullptr, bool  forceCurrent = false  ) const

inline

Extracts element solution vectors as nsd by nen matrices.

Parameters

[in]	nsd	Number of space dimensions
[in]	nen	Number of element nodes
[out]	u	First element solution vector (deformation)
[out]	v	Second element solution vector (velocity)
[out]	a	Third element solution vector (acceleration)
[in]	forceCurrent	If true, return the current values also if previous values are present

This method is intended for extraction of element-level solution vectors (deformation, velocity and acceleration for dynamics problems) on a matrix form, such that equivalent integration point values can be obtained by multiplying with the basis function value vector, fe.N. If the size of vec is 6 or more and forceCurrent is false, the previous values stored in positions {3,4,5} are returned, otherwise the current values stored in positions {0,1,2} are returned.
