I have generated a high order data for Quasi-3D: Homogeneous in z-direction (Number of homogeneous mode =8). Now i want to use the result as a initial condition for another simulation where i have (Number of homogeneous mode =7 or less). My solution is very smooth. The simulation is crashing with the segmentation fault error.

        EquationType: UnsteadyNavierStokes

        Spatial Dim.: 3

  Max SEM Exp. Order: 6

            Quasi-3D: Homogeneous in z-direction

      Expansion Dim.: 3

 Num. Hom. Modes (z): 6

     Projection Type: Continuous Galerkin

           Advection: explicit

           Diffusion: implicit

    Integration Type: IMEXOrder2

Any input from you will be very helpful.
