Meet the latest 2023 features

Introducing Experiment Builder

Experiment with any part of your process, without code!

New feature

Our previously known Scenario Manager has been retired, and replaced with something even better.

Simul8 has always been the fastest tool to learn, fastest tool to build and with this major update, we’re taking it to the next level.

Introducing Experiment Builder. Whether it’s simple what-if scenarios or bold process changes you are testing, our new Experiment Builder allows you to dynamically change parameter values and structural aspects of your simulations, meaning it’s easier than ever to quickly experiment with any part of your process – without the need for code!

This is only the first phase of our ground-breaking Experiment Builder release, watch this space for lots of new features coming soon.

Elevate your simulations with improved connectivity and customization

Connectivity update

Simul8 has moved to 64-bit!

With our 64-bit release, your simulations just got bigger and better. Simul8 can now talk to 64-bit enabled databases using our SQL functionality and 64-bit versions of apps such as Python – meaning improved connectivity for our users.

Feature update

Internal Spreadsheets have had a makeover

Our unique, powerful internal spreadsheet feature has had a makeover. Featuring a modern look, you can now create compelling interfaces to level-up your simulations! That's not all. Now with conditional formatting rules, formulas, and much more, it is easier than ever to personalize your data.

Transaction Log - Track every movement in your simulation

Simul8 already gives you access to results information in your simulation. Now, with our improved Transaction Log feature, you can further track every movement in your simulation, in just a few clicks!

Validate changes and identify patterns in your results through a single detailed log showing the movement of all Work Items, in and out of every Simulation Object. We have streamlined how the files work, so you have only one location to manage for Simulation Objects and Resources respectively, added more options for customization of information and made data produced by logs more accessible.

That's not all, once you have used the feature to create logs for your work items, you have a great source for further analysis. Slice and dice the data using an external tool like Excel or PowerBI to calculate, summarize and analyze data as well as see comparisons, patterns, and trends in your data.

The flexibility and depth of data available in the Transaction Log make it an ideal data source to level up your results even further and use it as a source for PowerBI and Python dashboards.

New integration

OptQuest for Simul8 - go from "what if" to "what’s best"

Optimization is a powerful addition to simulation. Simulation is all about saying what if, and experimenting. As you experiment you gradually work out the best way to configure your process for optimal performance.

But what if you could skip that lengthy process of experimentation? What if rather than getting a range of results you have to decipher, your simulation could tell you exactly the right combination to maximize performance?

With OptQuest you can. OptQuest lets you move from what if to what’s best. It lets you test thousands of different parameter combinations to find the best answer.

Latest innovation

Machine learning – automatically build your simulation rules from your data

Simul8 is already the fastest tool on the market, with the addition of machine learning we’ve just taken this to a whole new level! No more having to interrogate process owners and data sets to find the unique routing or timing rules, train your Machine Learning algorithm and let Simul8 do the rest!

We are the only simulation tool on the market to offer integrated machine learning functionality. Everyone lets you train data sets, or optimize end results. We let you use machine learning directly inside your simulation. Just call out to your preferred R or Python machine learning library to process your data set, and it’ll tell Simul8 what it should do next.

Combine ML with our other killer USP Process Mining, and you have the ability to build continuously up to date, real time digital twins.

New feature

Use Python and R to control your simulation

Already know Python and R, and would prefer to write your custom rules in those languages? With this release you now can.

You’ve always had the ability to control Simul8 via APIs in Python and R, so you can embed Simul8 in your tech stack. This release now lets you link a R and Python script to a custom distribution so you can read out to your R or Python script to let it do the processing for you. This lets you access machine learning libraries descibed above, but also to write your own custom code for Simul8 to obey.

New feature

Unleash the power of Visual Logic in Simul8

The first Simul8 2022 update introduced our new Visual Logic Editor Developer Mode, our latest release enables our users to further extend the power of Simul8 with code. Using Simul8's own scripting language built especially for simulation logic building, this release futher extends the power and flexibility of this unique feature.

In this release, we’ve added new modes into the Visual Logic Editor. Many of our users use Visual Logic, Simul8's scripting tool, to allow for deeper customization when needed. We've made big improvements to the inbuilt editor to make it easy to get started with VL, and have added an extra mode for the real power users to increase efficiency and flexibility.

3 Visual Logic Editing Modes


Logic Builder

The Logic Builder allows you to build up Visual Logic commands without the need to code, using our Visual Logic Editor wizard. Just double click on a command to begin!


Logic Writer

Logic Writer is what was known as the “Free Edit” mode. This allows you to write your commands as though you were writing in a text editor and helps validate each line of code before you move onto the next one.


The final, and newest, mode is Developer which allows you to write Visual Logic code quickly without the need of having to validate each line as you go. Any errors or code suggestions are listed in an Error box located at the bottom of the Visual Logic Editor. This allows for quick and efficient code writing and helps point you towards any errors that may be in your Visual Logic commands.
