Time Sequences allows you to make accurate time predictions of your system based on your components’ mode flows and Vali’s changes through time. These temporal representations are possible by tracking the evolution of your system in terms of Modes and Variables. 

Modes are the operating modes (conditions) that are defined on the Components’ Module which represents the behaviour of your components in each stage of a mission. If you want to know more about Modes and how to set them up, click here.

Variables are instances you create internally to the Time Sequence Module and allow you to analyze and monitor the evolution of certain indicators for your systems, such as Fuel or Power Consumption and Mass charts over time.

Setting up a Time Sequence is as simple as building a diagram. You just need to add nodes, which represent mode or a variable’s formula change to your system, in chronological order and set a condition (time) for each one of these events. 

Time Sequence Methodology

Within Valispace, you can create multiple time sequence simulations with different scenarios. The typical methodological flow of creating a time sequence is shown below and each step is explained briefly in each sub-sections.

Time Sequence common flow within Valispace

Users can change the flow based on their working ways. For example, the user can modify run settings and add variables before running the time sequences. Here in our documentation, we will cover the time sequence using the flow shown in the image above.

When a user enters the TimeSequence module, the left side (1) shows the lists of time sequences available and the right side (2) shows the setup and run process of the time sequences.

The time sequence flow is explained in the next articles.
