1. A management system of CAD data comprising: a storage unit which stores a set of the CAD data together with a set of one or more mesh conditions under which a CAE model is created from the set of the CAD data and a set of one or more analysis conditions under which CAE analysis on the created CAE model is performed associated with the set of the CAD data; and a process unit which, to perform the CAE analysis on the set of the CAD data, reads from the storage unit the set of the CAD data, and the set of the mesh conditions and the set of the analysis conditions associated with the set of the CAD data, creates the CAE model from the read set of the CAD data under the read set of the mesh conditions, and performs the CAE analysis on the created CAE model under the read set of the analysis conditions, wherein the process unit when performing the CAE analysis on the set of the CAD data, is configured to store in the storage unit a set of analysis information, the set of analysis information including an analysis time which has previously been taken for the CAE analysis using the stored combination of the set of the CAD data, the set of the mesh conditions, and the set of the analysis conditions, and wherein when a CAD model of the part associated with the set of the CAD data is selected among the displayed CAD models of the one or more parts through an input, the process unit is configured to display the set of the analysis information associated with the stored combination of the set of the CAD data, the set of mesh conditions and the set of analysis conditions including the stored analysis time before the CAE analysis is performed.
