Hi.

I am working on electrohydrodynamic droplet deformation.

I have a custom interFoam solver which includes an electric equation. I am getting prolate and oblate deformation based on fluid properties and electric potential. The results match the experimental data.

My next task is to calculate the deformation factor of the droplet. I am trying to use swak4Foam to get the deformation in x and y directions as indicated on https://openfoamwiki.net/index.php/C...ropletVelocity

I have added the following library files in controlDict as indicated on the main page of swak4Foam (https://openfoamwiki.net/index.php/Contrib/swak4Foam)

libs (
      "libOpenFOAM.so"
      "libsimpleSwakFunctionObjects.so"
      "libswakFunctionObjects.so"
      "libgroovyBC.so"
     );

I am able to blockMesh and setFields but I get this error once I put the solver.
