It is easiest if you start ANSYS via the launcher. In the launcher windows you can assign data base space and total work space for both interactive and batch jobs. Scratch space is allocated dynamically. Therefore, it is not very important what work space you choose. If the chosen workspace is too small for the problem size, ANSYS will allocate more memory as soon as it is needed and inform you with a pop-up message. If the model is big I usally choose the data base memory small for the solution to have as much real memory available for the sratch space. If the data base memory size is too small for the data base file, ANSYS will write data on a page-file, but I guess this does not have much negative impact on solution time. You can find more information on memory management in the docs.
