Pivoting has been activated for the Distributed Sparse Matrix Solver Warning

      Hello Everyone,

      I was modelling a frame made up of beam element and solid element but every time I ran it i get the error below

       *** WARNING ***                        CP =      9.453  TIME= 12:11:38

       Pivoting has been activated for the Distributed Sparse Matrix Solver . 

       The memory required may greatly exceed the predicted amount. In that  

       event, use the DSPOPTION command to change the memory mode and/or      

       memory size used by the Distributed Sparse Matrix Solver.              

       curEqn= 16431 totEqn= 68892 Job CP sec=    13.062

      Can anyone tell me what I have to do to get rid of this warning? It also says the memory has run out of space but I have a 16GB RAM but the required Memory is lower than my RAM. Can please tell me what is causing this?

      The initial memory allocation (-m) has been exceeded.                  

       Supplemental memory allocations are being used.                       


       Local memory allocated for solver             =   724.636 MB

       Local memory required for in-core solution    =   501.999 MB

       Local memory required for out-of-core solution =   182.348 MB


       Total memory allocated for solver             =  4370.937 MB

       Total memory required for in-core solution    =  3025.299 MB

       Total memory required for out-of-core solution =   975.839 MB

      My Model is as shown below

      Thanks.

      If you got a solution, you don't do anything. This is a warning not an error.nThis memory message is also very common and can be ignored.n
