Hi The model i have developed takes few minutes to simulate at a slow pace, some times it is difficult to tell whether it is still in simulation or not. So i have tried to add progress bar to my gui which i did successfully, but i am not able to sync the model simulation and progress bar. Can anyone guide me to solve this problem.

Simulink GUI already have a simulation progress bar at the bottom.

Isn't it sufficient ?

This blog post is old, but might have some ideas to help you:

Be sure to see the comments as well. They reference at least one FEX program that might help. This one looks promising (but I haven't tried it myself):

You can use Method Execution Event listeners to have the WAITBAR be updated in the PostOutputs callback of one of the blocks in your model. Please see the demo model "sldemo_msfcn_lms" to get an idea of how it updates a plot figure continuously - you can update a WAITBAR similarly.
