Does anyone know how to use Sparse mass stiffness and damping matrices which are extracted from Ansys to represent it State-space model identification using System Identification Toolbox™ ?
Dear Murana Awad,
Use mechss to represent second-order sparse models using matrices obtained from your finite element analysis (FEA) package. Such sparse models arise from finite element analysis (FEA) and are useful in fields like structural analysis, fluid flow, heat transfer, and electromagnetics.
Also i suggest you to see links on topic.
