hi simulation run failure and its showing that the solution matrix is not factorizable @PowerUsers_FEA https://www.simscale.com/workbench/?pid=4034866210047373767&mi=run%3A8%2Csimulation%3A1&mt=SIMULATION_RUN
Are you sure you want to perform a FE analysis? From what I can tell you want to make the propellers turn which either means you want to apply torque on a component to see the deformation or you want to see the flow around it. If it is the latter one I would recommend first optimizing your geometry by enclosing the propellers with a cylinder which will then be used for a so called MRF zone.
First, let us know what you are up to and we will jump back in to give you tips on your simulation
