Dear all,
I am trying to simulate a water/sand slurry inside a pipe. For this I first used the icoUncoupledKinematicParcelFoam solver. This worked fine and gave no errors. However, since the interaction of particle to fluid is important, I wanted to transition to using DPMFoam. When doing this I get an error, and in this error I see certain terms such as KinematicCloud, SphereDragForce, ParticleForceList. This gives me an idea about where the error is located, but I am unable to figure out how to solve it since I don't see why exactly an error occurs there.
Could someone help me out with figuring out what could cause the error?

I have worked it out and like to explain to those who may get this error.

I solved this by using the goldsmith tutorial (Which also uses DPMFoam) as a base and then adjust this into the simulation I want to do.
I changed the geometry, boundary conditions, etc and looked if an error occured when doing this. (At first I did this to see where I was wrong)
However, when I completely changed the tutorial into the simulation I wanted to do, the error did not even occur and the simulation worked.

So my suggestion to myself and anyone having this error is to first take a tutorial which uses the same solver. And then change the parameters step by step until it fully changes in whatever you wish to simulate.
