      Dear All
      I am new user of cosmosFloWorks. some time I get the error ""Not enough memory to continue the calculation. Failed to allocate requested continuous memory block of 1048592 (1.000 MB)" when i m running the CFD.

      Can anybody explain me why this error is coming and how to tackle with such kind of errors. please reply ASAP

      Thanks

          Hi Chirag: Yes it definitely means you need more memory. The software needs to setup "blocks" of memory for use in solving. Hope this helps. Regards, Tony.

            Dear Anthony,
            Thanks for your reply.
            U write in your mail that The software needs to setup "blocks" of memory for use in solving. Can you tell me how to setup the blocks of memory??

                Hi Chirag,

                Floworks will give that memory error whenever there are too many cells in the model. I have found that when solving a fluid flow and heat transfer model with 32 bit SW2008/FW2008 that anything over about 500,000 to 600,000 cells will cause the memory error.

                Reduce the number of cells and the error will stop.

                Adding more memory/RAM to your machine will help with the speed of solving, but will not prevent the error. I've heard that changing to 64 bit Windows and to 64 bit SW/FW will also allow much larger cell counts, but I don't know that first hand.

                Anyone out there running 64 bits care to brag about your largest successful cell count?

                Rich.
