I am getting this error when I run a cable simulation despite having 191Gbyte of RAM available:

===========================================

Storage using single precision

Memory requirement for MoM matrix: 2584 rows * 2584 columns = 6677056 complex numbers in total for all processes
For the MoM matrix, a memory of 6677056 complex numbers is used in total for all processes (i.e. 50.942 MByte)

Per process, 72.680 MByte of memory has been allocated dynamically,
which corresponds to 1.692 GByte in total for all processes together
(peak memory usage of 80.905 MByte per process so far)


CPU time for calculation of the MoM matrix elements: 1.325 seconds
ERROR 39822: Not enough memory available for dynamic allocation

===========================================

I recently had FEKO 2021 installed so I suspect something is not set up correctly with the license.

Thanks

    If you were using a student license, these are limited in memory but you would have received an error specifying this. 

    It could be due to very fine meshing inside of the cable mesher.

    Could you attach the full model file?

    Otherwise please contact support directly here.
