Hello <\/p>\n

<\/p>\n

I have been having issues with the memory for quite some time due to my comprehensive model. It has quite large at 2.5 million nodes, but the details and contact pairs necessitates a fine mesh.<\/p>\n

<\/p>\n

To mitigate the issue, I have already tried the following<\/p>\n

<\/p>\n

– running iterative solver<\/p>\n

<\/p>\n

– running out of core<\/p>\n

<\/p>\n

– increasing virtual memory<\/p>\n

<\/p>\n

– using msave<\/p>\n

<\/p>\n

however, even after all this I still get the error message: <\/p>\n

<\/p>\n

“There is not enough memory for the Sparse Matrix Solver used by the PCG <\/p>\n

<\/p>\n

 solver to proceed using the out-of-core memory mode.  The total memory  <\/p>\n

<\/p>\n

 required by all processes = 186543 MB.  The total physical memory that  <\/p>\n

<\/p>\n

 is available on the system = 115895 MB.  Please decrease the model      <\/p>\n

<\/p>\n

 size, or run this model on another system with more physical memory.”<\/p>\n

<\/p>\n

 <\/p>\n

<\/p>\n

Currently, I have 125GB physical memory and just added 80GB swap memory. However, the error message only reflects the physical memory while I have ample hardware to meet the requirement of 186543MB. <\/p>\n

<\/p>\n

I already allocated all the RAM in ‘solve process settings’ yet this issue is still persisting.<\/p>\n

<\/p>\n

Please help and thank you,<\/p>\n

<\/p>\n
