Hi there,

We were trying to perform screening analysis (Morris), uncertainty analysis (LHS), and global sensitivity analysis (Sobol’) with UQLab and model evaluation in a external program (non-Matlab)

As goal we would like to generate the set of input samples for the screening in UQLab, and perform the model evaluations externally (offline), by feeding those generated input factors to the model, computing the output, and subsequently feed the output to UQLab. The idea behind performing this externally and offline, would be to avoid the necessity to encapsulate our model in the UQLab function call, and hence avoid the necessity to integrate our model pipeline in the screening loop.

Is it possible to perform this decoupled approach in UQLab?

The same goes for performing uncertainty analysis with LHS and model evaluation in a external program.

Is it possible to generate a set of input samples for a LHS uncertainty analysis, and compute the model evaluations externally in offline mode? Or does the model evaluation have to be done necessarily encapsulated in the function evaluation in UQLab?

… and the same goes for a global sensitivity analysis : using the Sobol’ method (sorry for the redundancy :). Would it be possible this approach?

Thank you in advance for your reply,

Best regards,

Ricardo
