Error when calculating sliding mesh

    • AlvaroConchello

      Hi, I am starting with fluent and I ran into this problem when calculating the movement of a piston: "Error at Node 1: coalesce_rib_faces: can't interpolate data, zones of different type detected." I have tried using several different calculation setups and it always gives me this error at around 34% (almost half a cycle from looking at the volume chart) but I suspect it may have something to do with the time step size and the settings of the Dynamic Mesh.

      The geometry is a 12deg section of the complete piston.

      My mesh has an skewness value of 0.84 and orthogonal quality of 0.1996 with a total count of 79569 elements.

      Thanks in advance.
