Good afternoon all, As you may see in the title of the post, I've encountered a really strange crash in OpenIFS. The configuration is T159L91 + ORCA05 (coupled OpenIFS cy40 + NEMO 3.6 via OASIS3-MCT3, WAM turned off). … --- ## [OCP-Tool to generate OASIS3MCT input files and modify OIFS & runoff\_mapper input files for coupled simulations](https://forum.ecmwf.int/t/ocp-tool-to-generate-oasis3mct-input-files-and-modify-oifs-runoff-mapper-input-files-for-coupled-simulations/12173)

I'd like to share a v0.1 of something I called OpenIFS Coupling Preparation Tool (ocp-tool). I combined some of Joakims script to generate OASIS3MCT input files for a given OpenIFS grid with my script to modify OpenIFS … --- ## [EXTREMELY slow OpenIFS when coupled to NEMO using Intel MPI version 2019](https://forum.ecmwf.int/t/extremely-slow-openifs-when-coupled-to-nemo-using-intel-mpi-version-2019/12172)

Hi all I've got a coupled model, FOCI-OpenIFS, which consists of OpenIFS 40R1 + NEMO 3.6 + OASIS3-MCT3 + river routing (similar to EC-Earth). I'm running it on HLRN-IV in Goettingen, Germany, which has Intel Skylake … --- ## [OpenIFS Cy40R1 crash in GRIB\_API in a very long run](https://forum.ecmwf.int/t/openifs-cy40r1-crash-in-grib-api-in-a-very-long-run/12155)

Hi all I'm trying to run a pre-industrial control run with a coupled model, OpenIFS\_CY40R1 + NEMO\_3.6 + OASIS3\_MCT2.8. OpenIFS runs at T159 L91 resolution with a 1 hr time step. In IFS time, the model starts at 1950… --- ## [Windstresses over sea ice](https://forum.ecmwf.int/t/windstresses-over-sea-ice/12194)

Good morning, I would like to calculate the wind stresses over sea ice in order to send them to the coupler and the ocean model I'm using. The ocean model I use expects the windstresses over sea ice to be scaled down by… --- ## [Running open IFS with updated SST (coupled)](https://forum.ecmwf.int/t/running-open-ifs-with-updated-sst-coupled/12139)

Hi, I'm running OpenIFS (Cy40r1) for 2007, and it uses prescribed SST, which I believe comes from monthly EraInterim climo. Is it possible to run the model in a coupled fashion so that SST is generated and not taken fr…
