Dear all,

I am concerned with Initialization of Level set function at t =0 s during setting up the simulation using CLSVOF.

Problem is motion of a circular drop in a rectangular micro channel. I run the simulation with vof and results are fine. I am trying to simulate with CLSVOF but I dont know how to set the initial level set field (2D and 3D).

if i just active CLSVOF and set the remaining simulation as i did only for VOF case then my residual for first time step is attached here.
