i can mesh but it doesnt run

hi all,
i have a an assembly model to be analysed for frequency. this isbasically almost all components made of sheet metal. but theproblem is i can mesh the entire model, it cant run the analysis, ihave given the number of frequency as only 5, and direct sparsesolver, infact tried with all solvers available. But it does notsolve the problem. Solidworks gives a message that NOT RESPONDINGand gone is my analysis. Any help highly appreciated thanks.SolidworksSimulation
