Hi,

I'm looking into some multiphase simulations and Ihave a UDS corresponding to a solid phase, so thermally it evolves much slower than the gas phase. I would like to solve it every N>1 time-steps to reduce simulation times. Do you know of any way to do this?

I know that if i would treat the solid separately as a proper solid in Fluent I could use a built-in time-scale factor, however the setup is pretty much already layed out in this way and several dependencies rely on this configuration.

Thanks in advance!
