Ansys Circuit model with HFSS Link, how to run optimization in parallel?

[maxkovalev23]

I am trying to optimize a waveguide divider with one if it's ports loaded with a waveguide filter. Simulating a full wave model would be compute-heavy, so i decided to try loading one of the divider ports with Touchstone .s2p of a filter. The only way of doing this in AEDT that i found is creating a circuit model and putting my HFSS model in as a subcircuit and putting an NPORT node with an .s2p to one of the outputs and then optimizing Nexxim Linear Network setup with Dynamic Link variables.

I have configured Circuit HPC to run 3 jobs in parallel, but when i start the optimization three jobs appear in progress panel, but only one of them being simulated, while others a re hanging there with "RUNNING" status. Is that me configuring something wrong, or is it AEDT not behaving the way it is supposed to?

AEDT 2025R2 btw
