Hi everyone. I am attempting to run the idealized LES test case "test/em_les" (WRF v4.4.1) with both gas and aerosol phase chemistry. Previously, I have successfully run LES simulations with CBMZ gas phase species (chem_opt = 6). However, when I switch to using one of the coupled CBMZ/MOSAIC sectional chemistry options (e.g., chem_opt = 7) I encounter segmentation faults that occur as soon as the simulation initializes. Note that the simulation only encounters a fatal error when I turn aerosol chemistry on (aerchem_onoff = 1), things run fine without the MOSAIC aerosol chemistry active.
I wanted to ask whether this is due to user error (perhaps incorrectly configured namelist parameters - please see the attached file) or whether this is a limitation of WRF-LES in terms of representing MOSAIC aerosol chemistry?
I've also included an example rsl.error output - this particular situation was run on 24 cores, but I have also tried running with 64 cores.
Thank you for your help!
