  1. hi @Prakash Pagadala I just checked in on my calculation and it has completed perfectly, without errors. thank you for your help kind regards, KBE
  2. @Prakash Pagadala, yeah this calculation might take some time.
  3. yes.. i just launched the calculation with out-of-core. this might take some time. the problem with the memory space seems to be ok.
  4. should I run with out-of-core instead of in-core? Current Memory (RAM) : 16000 MB (Note: MUMPS Solver Allocates Memory Separately.) Estimated Minimum Memory (RAM) for Out of Core Solution : 15032 MB Recommended Memory (RAM) for Out of Core Solution : 15372 MB Recommended Memory (RAM) for In-Core Solution : 23951 MB (Note: Memory for MUMPS Solver is Included in Estimation.) DISK SPACE ESTIMATION INFORMATION : ----------------------------------- Estimated Disk Space for Output Data Files : 556 MB Estimated Scratch Disk Space for In-Core Solution : 584 MB Estimated Scratch Disk Space for Out of Core Solution : 9163 MB
  5. heres what i got after trying with tempdir. It's exactly the same thing. Current Memory (RAM) : 12482 MB (Note: MUMPS Solver Allocates Memory Separately.) Estimated Minimum Memory (RAM) for Out of Core Solution : 15032 MB Recommended Memory (RAM) for Out of Core Solution : 15372 MB Recommended Memory (RAM) for In-Core Solution : 23951 MB (Note: Memory for MUMPS Solver is Included in Estimation.) DISK SPACE ESTIMATION INFORMATION : ----------------------------------- Estimated Disk Space for Output Data Files : 556 MB Estimated Scratch Disk Space for In-Core Solution : 584 MB Estimated Scratch Disk Space for Out of Core Solution : 9163 MB ************************************************************************ For minlen, what value should I put?
  6. I tried with tempdir as well and i have the same issue.
  7. Prakash, I tried launching the calculation with fixlen but each time I enter a value for the memory, it requires more and the calculation fails. I first tried with 500, it required 540, so i entered 600 then it required 820 so then i entered 1000 and this is what i got. *** ERROR # 7001 *** Not enough memory for preprocessing (total number of nonzero terms has not been determined) OptiStruct was executed with fixed memory size, which was not enough for the given run. Please allocate more memory or use automatic memory allocation feature in OptiStruct. This error occurs in module "prpdrv". ************************************************************************ RESOURCE USAGE INFORMATION -------------------------- MAXIMUM MEMORY USED 1000 MB MAXIMUM DISK SPACE USED 1 MB ************************************************************************ ************************************************************************ *** ERROR # 7000 *** Not enough memory for completing the run current memory (in MB) = 1000 required memory (in MB) = 1070 OptiStruct was executed with fixed memory size, which was not enough for the given run. Please allocate more memory or use automatic memory allocation feature in OptiStruct. The problem is, I did a similar calculation with the exact same configurations and it worked fine. Regards, KBE
  8. Hi Prakash, I tried the first two steps that you mentioned yesterday. Closing all applications running and cleaning the disk, but I still had the same issue. Where can I find the fixlen option? Is it in optistruct options or do I have to define it in a card? Currently, my collegue is using the licence so I have to wait till he is done. I will try what you said and let you know. Thank you KBE
  9. Tried this but there still isnt enough memory space. Is there another option?
  10. Yeah i could, but it takes hours for the calculation. Should i just run it and send you the memory information?
  11. @Prakash Pagadala, See below for the global_output_request card details: everything else is not active.
  12. Did you want the information below? MEMORY ESTIMATION INFORMATION : ------------------------------- Solver Type is: Sparse-Matrix Solver Direct Method Current Memory (RAM) : 12498 MB (Note: MUMPS Solver Allocates Memory Separately.) Estimated Minimum Memory (RAM) for Out of Core Solution : 15048 MB Recommended Memory (RAM) for Out of Core Solution : 15388 MB Recommended Memory (RAM) for In-Core Solution : 23967 MB (Note: Memory for MUMPS Solver is Included in Estimation.) DISK SPACE ESTIMATION INFORMATION : ----------------------------------- Estimated Disk Space for Output Data Files : 556 MB Estimated Scratch Disk Space for In-Core Solution : 1396 MB Estimated Scratch Disk Space for Out of Core Solution : 9975 MB ************************************************************************ As I am running another calculation right now, I have 46Gb still available in my main disk.
  13. Hi @Prakash Pagadala, Is this what you meant? or did you want the output data requested in the global_output_request card?
  14. I have done a model similar to this. The only difference is the size of the two cylinders that I am trying to encase. I have already defined the necessary SPCs and the SPCDs for those SPCs. It worked with the first model but not working with this. I double checked all the constraints as well.
  15. Hi @Nachiket Kadu The disc displacement is made of SPCDs.
