LMS Virtual.Lab Model Updating is a model correlation and updating tool that improves simulation model quality based on reference data. It easily handles incompatible geometries that occur when comparing test and FE models. Models can be correlated geometrically through alignment, sizing and mapping procedures. The solution provides numerical tools as well as tools to check orthogonality between two models.

LMS Virtual.Lab Model Updating is a model correlation and updating tool that improves simulation model quality based on reference data. With LMS Virtual.Lab Model Updating, analysts can make models that match reality more closely. FE models are first correlated with reference models, which are typically test models, but can also be FE models. The next step is to compute dynamic property sensitivity with respect to design parameter uncertainties. This can be done by inserting a Nastran Sol200 case from LMS Virtual.Lab Desktop. In this way, users can easily define element group properties for sensitivity analysis, including material and property data. Dynamic targets can be the total system mass, a specific eigenfrequency that is poorly correlated, vibration levels for unit load conditions or mode shapes. Sensitivity information is then used to update or optimize the Nastran model to match real-life condition better. For non-Nastran users, the FE model can still be updated or optimized, using LMS Virtual.Lab Optimization.
