Mapping distance not available due to empty partition

Using preCICE
, , ,
1

Hello. I used to precice 1.6.1 for FSI simulation. Simulations completed with no error. Now I want to use precice 2.3.0 for same simulations. I installed and tested tutorials there are no error. I use nearest-neighbor mapping for my case and there is error “Mapping distance not available due to empty partition.” and fluid stuck. I tried rbf-thin-plate-splines mapping this error does not occur but fluid still stuck. Full error text;

(occur all process)

Process #1/5: Does not work on wetSurface
Process #1/5: Does not work on the wet surface at all.

How can I fix this issue? Can someone help me? Thanks.

I actually think that this is the wrong process to look at. The first part of the message:

Process #1/5: Does not work on wetSurface
Process #1/5: Does not work on the wet surface at all. 

---[precice] Mapping distance not available due to empty partition.
---[precice] Mapping distance not available due to empty partition.

essentially says that this parallel partition does not participate in the coupling.

Then, a floating-point exception appears at partitioning:

[Harun:00195] Signal: Floating point exception (8)
[Harun:00195] Signal code: Integer divide-by-zero (1)

My first step would be to export the preCICE meshes and try to understand if the meshes are defined correctly: Export configuration | preCICE - The Coupling Library

Otherwise, if you only changed the version, I cannot imagine what could be wrong. I guess you already went through the list of configuration changes: Porting adapters from preCICE 1.x to 2.x | preCICE - The Coupling Library

I install the new version of precice on clean ubuntu. I did not upgrade. Now I install the old version of precice and my configuration is working. I changed the precice-config.xml with the new version. I don’t think wrong installition because the perpendicular flap tutorial work with no error. I am not sure where I am wrong.
