Hi users,
I try to model a multiphase flow with lagrangian particles and now I'm focusing on the wallinteraction. I found something on the internet that the restitution-coefficients (normal and tangential) depends on the impac velocity and the Webernumber. For calculating the WeberNumber and the coefficients I have written a 3 fieldfunctions (normal, tangential, webernumber) which uses the boundarysampling on the impacting wall. It all works and I can display each fieldfunction in a scalarscene. Now I insert the fieldfunction into my properties, but there occurs an error: "Unable to compute field function 'NormalRestitution' on parcels of Lagrangian Phase: Oil. Please check that function is defined here." I can use a particle average report, but thats not the best solution if you have multiple particles on one boundary. does anyone have an idea, how to fix this? Thank you, Nils |
