HFSS15: Distributed Memory Solutions with HFSS

When properly configured, and with Enable Use of Solver Domains selected as a Setup option, the HFSS solver uses the industry standard Message Passing Interface ("MPI") and can perform solutions that distribute memory use across machines in a cluster or network. Memory used by the MPI-enabled HFSS solver is therefore limited by the set of machines that are available rather than the shared memory available on any single machine. This allows you to simulate larger structures than before and to optimally reconfigure the cluster of machines for the problem at hand.

To use the distributed memory solution in HFSS you will need to install HFSS and MPI software from one of the supported third party vendors on all the machines you intend to use. You may need to set passwords depending on the MPI vendor for authentication on the machines. Settings within HFSS are used to turn on distributed memory solutions and define the list of machines you intend to use. If an HFSS problem involves solver domains or a finite array, then frequency sweeps will not be done using DSO. Also, DSO for Optimetrics will not be allowed.
