Hello everyone!
1. Model description
I am trying to simulate a classic fluid-structure interaction (FSI) problem, specifically the deformation of a flexible cylinder under incoming flow. I’m using OpenFOAM to solve the fluid domain and CalculiX to solve the structural domain. Given that my model has a high length-to-diameter ratio and the Reynolds number is quite high (requiring LES simulation), I’m attempting to reduce the computational load by using a 3D fluid mesh coupled with a 1D structural mesh. For the structure, the mesh consists of B32R beam elements.
2. Geometric-multiscale with parallel for OpenFOAM and single-core for CalculiX
In the process of configuring geometric-multiscale, I have tried both axial and radial mapping methods, setting up parallel pimpleFoam for OpenFOAM, but encountered the following error messages(upper one axial, lower one radial).
---[preciceAdapter] Loaded the OpenFOAM-preCICE adapter - v1.3.1.
---[preciceAdapter] Reading preciceDict...
---[precice] e[31mERROR: e[0m An unexpected exception occurred during configuration: Axial geometric multiscale mapping is not available for parallel participants..
---[preciceAdapter] Loaded the OpenFOAM-preCICE adapter - v1.3.1.
---[preciceAdapter] Reading preciceDict...
---[precice] e[31mERROR: e[0m An unexpected exception occurred during configuration: Radial geometric multiscale mapping is not available for parallel participants..
3. Geometric-multiscale with single-core for both OpenFOAM and CalculiX
Later, I tried running OpenFOAM and CalculiX using single-core computation, and the previous error did not occur again. However, the terminals of OpenFOAM and CalculiX encountered the following errors, respectively.

4. Attatched files
The structure mesh, setting files for OpenFOAM and CalculiX, precice-config, the logs from parallel-implicit test and serial-implicit test are attached.

Could anyone advise on the possible reasons and how to properly set up the precice-config and the other files? Also, is this 3D-1D FSI coupling approach with OpenFOAM and CalculiX feasible?
Thank you in advance for any insights or assistance you may offer!
