Nastran SOL 600 退出序列号4031怎么解决

CS_520-1

采用sol600，计算过程中遇到这样的问题，然后程序退出了 Exit number 4031，请问下要怎么解决

             memory increase from   78396311 to   78412835 words failed


*** error: memory request of        78412835 failed during
           sizing for operator matrix

Unable to obtain the memory requested during a dynamic
             memory request. This can be due to the following reasons:
            
             1) The maximum allowed amount of memory is exceeded.
                This can be set in the solver option for certain solvers.
                See Volume C, solver model definition option.
            
             2) There is not enough free memory on the system.
                If the memory available is not enough for an in-core
                solution, Marc will attempt to perform the
                solution out-of-core. In this case, some data which
                normally would be stored in memory is stored on the hard
                disk (which could slow down the analysis considerably).
                The memory request will fail if there is still not enough
                memory for the analysis.
