Thermal dynamically memory allocation error running LS-Dyna in supercomputer

    • brian3093

      Hi, I am a PhD student at Texas A&M University.

      I have a memory allocation problem running LS-Dyna in supercomputer

      It is a drilling simulation and it is structural_thermal_coupled problem.

      I submit the job using sbatch file in supercomputer and the memory allocation pops up. It says


       S t o r a g e   a l l o c a t i o n   


       Thermal dynamically allocated memory   :        0


       Memory required to begin solution      :    1187K

       Additional dynamically allocated memory:    9118K

                                         Total:      11M


       When error termination was triggered, this processor was

       in unknown location          0



      I was wondering if somebody knows how to allocate thermal dynamically memory.

      Thank you.

      I think the error message overall indicates a either a bug in the program or an issue in the model that was not caught appropriately by the software. You would have to try out a recent Dev or recent release version. Please ask your license point person (e.g. your professor) to contact LSTC for access to a recent version if you don't have that already.
