# 10 Best Free Monte Carlo Simulation Software For Windows

Here is a list of **best free Monte Carlo simulation software** for Windows. These software use Monte Carlo techniques for the evaluation of different problems in different fields. Monte Carlo methods are computational algorithms used for obtaining numeric results which assess in risk analysis and decision making.

As you explore these Monte Carlo simulation software, you will find out that each of these is used in distinct application. These applications include **simulation of building fires, computing a project’s time, Monte Carlo ray tracing, root locus analysis, computing eigenvalues, Markov chain Monte Carlo simulation, computing financial estimates,**** Monte Carlo simulation for trading systems**, etc. You can view different charts related to particular simulation and numerical results too. For example, in simulation of building fires, the software shows

*Histograms, Cumulative Density Plot, Time Series Plot, Percentile Time Series Plot,*and

*Sensitivity Analysis Plots*graphs. You can also save the output charts.

### My Favorite Free Monte Carlo Simulation Software For Windows:

As I have already mentioned that these software are used for completely different applications. Hence, you can go for the one on the basis of your requirement. I personally liked **B-RISK** as it provides a good number of graphical output to perform building fire simulation.

You may also like some best free Statistical Analysis Software, Econometric Software, and Data Mining Software for Windows.

## B-RISK

**B-RISK** is a Monte Carlo simulation software for simulating building fires. You get various Monte Carlo results and graphics as simulation results to analyze in it. For data visualization, you get graphs including ** Histograms, Cumulative Density Plot, Time Series Plot, Percentile Time Series Plot, **and

*. You can visualize data for*

**Sensitivity Analysis Plots***Upper/Lower Layer Temperature, Layer Height, FED Gases, FED Heat, Visibility, Rate of Heat Release, Sprinkler Activation Time, Frequency Plot,*etc.

### How to perform Monte Carlo simulation to simulate building fires:

- First step it to set up a new project by selecting user mode as
*NZBC-VM2*(supports verification methods for fire safety design) or*Risk Simulator*(fire risk simulation). You can also set different project settings such as*layer assumptions, combustion parameters, interior temperature, exterior temperature, relative humidity, activity level, tenability, flame area constant, solver settings,*etc. - Now, you can add building description by adding
(wall vents, ceiling vents, mechanical vents), and*room designs, ventilation*(sprinkler and heat detectors and smoke detectors).*sensors* - You can then
**setup fire specifications**which include*fire selection, combustion parameters, CO/soot, fire object database,*etc. - Next, open console and create a base model by configuring project parameters like
*maximum number of iterations, maximum simulation time, MC output interval,*etc. - You can view output in the form of various graphs mentioned above. You can copy any of the graphs to the clipboard. It also provides an option to
*export data to Excel*, but it didn’t work fine during my testing. - It provides a
**Smokeview**tool to visualize model geometry with wall and ceiling vents and numerical calculations generated by fire models.

Overall, it is a nice software to simulate building fires using Monte Carlo techniques.
