eval_dH_dX

eval_dH_dX(dH_dR: MatrixBase, dX_dR: MatrixBase)[source]

Evaluate derivatives of shape functions with respect to undeformed real space coordinates.

Parameters:

dH_dR – matrix of shape (n, d); derivatives of shape functions with respect to reference space coordinates
dX_dR – matrix of shape (d, d); derivatives of undeformed real space coordinates with respect to reference space coordinates

Returns:

symbolic matrix of shape (n, d)
