Hello  
Hope you are all well  
I was working on an FSI case setup using OF and CalculiX for flow over an elastic sphere and received an error that I noticed a few other people got in the posts below.

[preCICE using new Mesh Motion Solver - Official adapters and tutorials - preCICE Forum on Discourse](https://precice.discourse.group/t/precice-using-new-mesh-motion-solver/857)

This is the error I got when executing ./run.sh for the fluid side:

I am using snappyHex to generate the fluid mesh. Is that a potential reason why I am getting this error? I have attached my case folder below if that helps.  
[sphere\_0810.zip](https://precice.discourse.group/uploads/short-url/iev7zpHJO9mESeQb3JRbsMdrcas.zip) (380.8 KB)

Would appreciate any assistance.

Hi @mishal49,

can you try if the latest develop branch of the adapter works? This PR may have helped: [Displacement reading: Allow mesh motion solvers without a pointDisplacement field by solids4foam · Pull Request #241 · precice/openfoam-adapter · GitHub](https://github.com/precice/openfoam-adapter/pull/241)

(see also [I was asked to try a Pull Request. How can I do that?](https://precice.discourse.group/t/i-was-asked-to-try-a-pull-request-how-can-i-do-that/38), although this PR is already merged and you can just `git pull` and `git checkout develop`, then `./Allclean` and `./Allwmake`)

Hi @Makis  
Okay. Let me try this.  
I did switch the fluid mesh to one generated from a commercial software and still encountered the same error so does that mean that the adapter is still the issue?

Hi @Makis  
I compiled the latest adapter and updated the dynamicMeshDict and preciceDict files. I now encounter the same error much earlier.

Hello  
Any suggestions on what the issue could be?

This is the error message, essentially meaning that either there is no such field, it is named differently, or it has a different type. Assuming that you are now using solids4foam, are you using the latest develop version of it? Have you modified your `dynamicMeshDict` compared to the files you attached above?

I am using Calculix for this case and yes, I did modify the files to follow similar formatting to the ones shared. I have attached a link to the case and all relevant files.

I don’t have access to this file, but I guess only a few files are relevant.

I don’t know if you noticed already, but we recently added a solids4foam case for our perpendicular flap tutorial: [Perpendicular flap | preCICE - The Coupling Library](https://precice.org/tutorials-perpendicular-flap.html) Maybe it also helps comparing the configs.

I do not see a folder for solid4Foam in the flap case in the tutorial repository:

Running your case, I also get the same issue.

Can you run the perpendicular flap tutorial `fluid-openfoam` case, configuring with RBFMeshMotionSolver, [as Philip describes here](https://github.com/precice/openfoam-adapter/pull/241)?

I guess one aspect we have not checked is whether simpleFoam works at all (it should), as we mostly use pimpleFoam in our FSI tutorials.

You are right, as we have not yet released a new version of the tutorials (but the website points to “develop”, which can be misleading in situations like this). Just go to the `develop` branch: [GitHub - precice/tutorials at develop](https://github.com/precice/tutorials/tree/develop)

I tried this and still encountered errors.  
Can I use the RBF solver only with solid4Foam?  
Do I have to stick to other solvers if I am using CalculiX?

The same error, or something else?

> Do I have to stick to other solvers if I am using CalculiX?

There is probably a misunderstanding here. The RBF Mesh Motion Solver is provided by solids4foam, and you can use it in your fluid solver, if you have solids4foam installed. It does not matter what solver you have on the Solid side.

I see. I do not have Solid4Foam installed so I am not able to use this solver yet.  
I can try and install to see if it makes a difference.
