Controls the storage and retrieval of modal data such as eigenvalues and eigenvectors used in dynamic response analysis. The default value DELETE will purge all modal data when the program terminates normally. When set to STORE, the modal database is stored in a single file with the same base name as the Model Results Output File and a .MDB file extension. When set to FETCH, the database specified by the MODALDATFILE directive is retrieved and the eigenvalue extraction phase is skipped. When set to UPDATE, the modal database will be retrieved and stored. |
