Hello team,
I am trying to run a simulation with grid refine factor 7. I know this is
significantly large and any improper code will raise memory issues. I am in
fact getting memory issues after completion of first time step and I am not
able to pin point where I probably am making a mistake. The below is the
error message.
periodic facepairs: 1
Number of active cells: 9437
Number of degrees of freedom: 8586756 (6440067+2146689)
Solving for Displacement:
rhs_norm : 0.0414408 Number of CG iterations: 55
rhs_norm : 3.98697e-05 Number of CG iterations: 121
CONVERGED!

</home/rnp/Software/dealii-build/tmp/unpack/deal.II-v9.3.0/source/base/utilities.cc>
in function
void dealii::Utilities::System::posix_memalign(void**, std::size_t,
std::size_t)
The violated condition was:
ierr == 0
Additional information:
Your program tried to allocate some memory but this allocation failed.
Typically, this either means that you simply do not have enough memory
in your system, or that you are (erroneously) trying to allocate a
chunk of memory that is simply beyond all reasonable size, for example
because the size of the object has been computed incorrectly.
In the current case, the request was for 134217728 bytes.
I would highly appreciate any pointers regarding this.
Thanks in advance,
Raghunandan.
