Parameters:
eid - element id

ci - block column 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[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.
