I am running a modal analysis/frequency response analysis. I am using the same meshed components from a previous, successful analysis run; but I replaced 2 meshed components with updated CAD changes. I cannot see anything wrong with the meshes or the set up. However, the analysis keeps failing and the only explanation in the 'out file' is Error "eigdrv" and OptiStruct Error "3428". Does anyone know what these errors mean or reference?
