Handling error code 33132: "Not enough memory available for an in-core solution..."

Having memory issues simulating the performance of an antenna close to the human body. Obtaining 
'Error message 33132: Not enough memory for an in-core solution. Out-of-core storage of the MoM 
matrix is not supported with the FEM'
-----------------------------------------------------------------------------------------------------------------------------------

According to the readme file for the model I imported, at least 10GB is needed to run the 
simulation, and it seems my system is not allocating enough memory to simulate the problem as 
shown from the .out file:

Memory:   Unlimited, system allows maximum usage of 5.288 GByte
          (for parallel runs memory limit is per process)
          (installed memory 31.926 GByte, thereof free 23.463 GByte)
------------------------------------------------------------------------------------------------------------------------------------

Does anyone have any advice to fix this issue?

    Hi Daniel

     

    The message states 5.288 GByte is needed per process (i.e. per parallel process).

     

    For FEM solutions, usually you have to enclose the model with surrouding 'air' dielectric (a dielectric with permittivity of 1) to reduce the memory requirement.

    This trick can be seen in the two videos below which can be found here. 

    The first one on the 2nd row, and thereafter watch part 2, which is the one on the top right. 'Stacked dielectric resonator antenna'

    If you have tried this already, please attach your model, or at least, please give a few screenshots.

    Hi Mel / Altair Support,

    Regarding what was said about enclosing the model in an airbox, is there a way to use a farfield source with FEM?

    Thanks,
    TJ
