How to avoid algebraic loops in model?

I want to avoid algebraic loop in my model. My model is running in discrete time step with step size of 100usec. To avoid loop I tried using unit delay which resulted in unexpected results. so using delay is not an option for me. Also tried using IC block from simulink library for initializing the signal value but unable to avoid any loop. Please suggest some ways to avoid algebraic loops an discrete time system.

Here are some good tips for algebraic loops:
If you are running a fully discrete model you can explicitly set all the sample times too 100 usec, run the model at a faster rate and set the unit delay to that faster rate so the data will be available at the beginning of the next time step. Not 100% sure how well that will actually work though.

Hi,
I have the similiar problem.
I can avoid algebriac loop using both "Initial condition" block and "unit delay" block.
However, using unit delay, the system response is different AND unfortunately, I can only build an .exe file by using unit delay option.
For .exe file, initial condition block does not remove algebriac loop. :(
Can you please help me with this?
Thanks.
