Cycle problem

** ERROR: BLOCK D2 is not in mass balance. Mass inlet flow = 0.49359457E+03, mass outlet flow = 0.49293057E+03; relative difference = 0.13470604E-02. This could be due to a leaky stream, or the stream flow may have been altered by a FORTRAN statement, a transfer operation, or a balance block after that block was executed. ** ERROR: The convergence block $OLVER01 did not converge properly during the final iteration. Could anyone help me understand what this means?

There is a material imbalance in the tearing flow; adjust the initial values or optimize the looping method

First, break the loop, directly provide an initial value for the loop, and continuously assign the computed value to this initial value, thereby creating a difference between the two values

Or use a simpler tearing flow, which converges more easily
