Hi Guys. I have modeled a fate and transport system of contaminants in subsurface media with Simulink. This model consists of Subsystem 1 and Subsystem 2. The Problem is when I run the model, both Sub1 and Sub 2 run together but I want that the clock in Sub 2 starts with a delay respect to Sub1. In other words I want Sub 2 starts when sub 1 hit a specific time. I would be grateful if you help me through this.

Use "Enabled subsytem" block for both Subsytems.
Updated file attached. Sub system 1 tuns from 0-75s. Subsystem 2 runs from 75-100s taking the value from subsystem1 when t=75s. You can edit the trigger point as required.

By the way my email is siavash.sedighian@gmail.com
Oh by the way the second compartment would start at t=75. Can I do anything that the 75s in subsystem 1 becomes 0 s in subsystem 2??

reuploaded.
Subsystem1 starts at t=0, subsystem2 starts at t=75
For display purpose you can time shift the t-axis using an x-y plot instead of the scope.

hi. you need to develop a scheduler where in the subsystem2 gets triggered based on subsystem1

As a matter of fact everything would be just fine if I can transport my signal backward. I can not transport backward just forward as long as Transport block does not accept any negative value. Do you have any answer for me? I would be very grateful for your help.

Use an embedded matlab function to create a rule to overwrite negative time values. Attach the mdl file to investigate further

Here is my model. I need to eliminate all the zero elements before the "Travel time trough unsaturated zone" and shift my signal from "t=Tunsat" to 0. Would you mind help me?

I need to shift the signal to zero and then proceed it to the next subsystem. I don't want them to run simultaneously.
