The function computes initial values of the given quantities at each integration point of the element from the nodal values given by the parameter nodval. Initial condition types must be the same for all nodes of the element.

Parameters:

	eid	- element id
	ri	- block row index

	nodval	- nodal values of particular initial conditions. nodval[i][j] represents value of j-th initial condition at i-th node of the given element.
	ictn	- array of types of initial condition for each node of element. The type of initial condition determines which values are being specified in the node. (ictn[i] & inistrain) returns nonzero if nodal values of initial strains are specified (ictn[i] & inistress) returns nonzero if nodal values of initial stresses are specified (ictn[i] & iniother) returns nonzero if nodal values of initial values of eqother array are specified (ictn[i] & inicond) returns nonzero if nodal values of other initial conditions are specified

The function does not return anything.
