问题
I have a sample model(shown below) which consist of a from workspace block. It contains a workspace variable variable1(timeseries signal). I am changing the data of variable1 during simulation but model is not updating the current value of variable1. It's update only when I stop and restart the simulation but I want it to update during runtime only. Can anyone help me in handling this problem?

This is not really how Simulink is designed to work, so there's no easy way to do this. Simulink only checks only checks the workspace for values during model initialization at the start of the simulation. The best thing to do is to use set_param, as in:
set_param('untitled/From Workspace',' VariableName','variable1'); % put the correct path to your block
This is not changing anything in how the block is parameterised, but forces Simulink to parameterise the block with the new values of variable1. Because variable1 is a timeseries object, I am not sure how well this will work, but it's worth a try.
For more details, see this discussion on MATLAB Central.
