long simulation time issue

Dear support team,

Recently, we run a simulation for a absorber placed between sphere two horn, we would like to get S parameter from this setup.

However, this simulation was stuck as shown in attached figure, LU decomposition of the matrix, for almost two days.

And also I think our server system is good enough for this simulation with 512 RAM.

In this simulation, how can I decrease the simulation in hour through the setting, I think it is must be something wrong in my setting for absorber in this simulation.

Because it is one of an urgent studies for a paper, pleas help us solve this issue ASAP, appreciated.
