[CIG-LONG] Problem about the Mesh in Gale

[feng lin]

Hey everyone,

I'm now running some model to simulate some extension precess with Gale2.0.
And I met some problem with the number of elements in the model.

I set up a 2D problem and in the input file:

{
...
    "nx": "16",
    "ny": "4",
...
}

When I plot the v-mesh and pressure-mesh with VisIt2.5. I got both 32
elements at x direction and 8 elements at y direction.

I can understand that for the v-mesh the number elements in the x direction
should be 2*nx (32), y direction is 2*ny (8). The v -mesh is quadratic
elements (Q2) according to the manual.
But I couldn't understand why for the pressure-mesh the number of elements
in x and y direction are 2*nx (32), and 2*ny (8). As the pressure mesh
should be discontiuous linear elements(P-1) according to the manual, I
think the number of elements in x, y direction should be nx(16), xy(8)

Anyone can help me out?

File attached is the inputfile.

Thanks,

Feng Lin
