HI Mehak,

Did anyone send you a response to this? Using 7 homogeneous modes is quite an usual number since it is not a binary number. Does it work if you use mode=4?

Cheers,
Spencer.

Dear all,

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.

Thanks 
Mehak naina oberoi
