Monte Carlo simulation support

Cameo Simulation Toolkit introduces built-in support for Monte Carlo analysis. This allows managing uncertainty and estimating how random variation of sensitive parameters affects the overall performance of the system being modeled.

• Value distributions are specified using SysML «normal» and «uniform» stereotypes on Value properties.
• The number of initializations and runs of any selected target is specified in Simulation Configuration.
• Values of every iteration can be recorded using CSV Export configuration.
• A new histogram plot can show estimated distribution of the values of interest.
• The MonteCarloAnalysis block provides context, allows capturing and verifying statistical results (mean, standard deviation, and probability of out of spec), and represents them in Instance tables.
• The HingeMonteCarloAnalysis sample model demonstrates this capability.

New MATLAB integration

MATLAB R2016b introduces a new official Java API, providing a faster and more reliable interface for CST to communicate. Mac users should be especially happy, as the new API no longer requires disabling System Integrity Protection (SIP). This new integration is available in CST 18.5 SP2 too. Learn more about new MATLAB integration >>

FMI 2.0 support

FMI 2.0 version models can now be imported and co-simulated. Simply drop an *.fmu file into the IBD diagram for interconnections and specify the end time and clock step in Simulation Config. Thanks to customer feedback, the co-simulation master algorithm is enhanced with several small improvements, too. Learn more about FMI 2.0 support >>

More time units

To support a wider variety of the systems and behavioral scenarios, smaller (nanosecond and microsecond) and larger (day, week, month and year) time units are added. Learn more about supported time units >>
