Uncertainty Quantification (quoFEM) / QuoFEM Sensitivity Analysis
« on: December 16, 2022, 10:38:39 AM »
Dear all,

I'm running sensitivity analysis in QuoFEM, and I have a question related to "UQ Engine".
In QuoFEM, you can perform sensitivity analysis by using either Dakota or SimCenterUQ  UQ engine.
I run the same case (same RV and number of samples)  with both UQ engines but I don't get the same results regarding the sensitivity of each parameter (main and total).
My question is, which is more accurate or reliable regarding the sensitivity analysis?
Should both UQ Engine provide the same results or is normal that the results are different?
I attached the results from both analysis for your consideration.

I have a model to calculate maximum load in column.
I'm trying to run Monte Carlo simulation to get maximum load using random variables, but I'm getting this error:

Error Running SimCenterUQ: Error running FEM: results.out missing in workdir.23. *** Message from the FEM engine in workdir.23 says "" 

best regard,
