Error - Initial pressure condition using topography

[Thomas]

Hello,

In order to set initial pressure condition, I fixed first layer at atmospheric pressure.

As top boundary, I used topography with separated file input.

My model is “2D” :

X : 0=>3000 m, Y : 0=>1 m and Z : top topography=> -3000 m, with default initial conditions for 1 material.

When running, I've got error : “simulation halted prematurely” when using a too high mesh grid ( 15 x cells mesh or more) (Figure 1) but no problem with low mesh grid, 10 x cells mesh or less (Figure 2).

Could you help me to resolve this problem ? I try to used less topography data without success.

However, without any topography (Zmax = 0), there is no problems for running , with high or less cells mesh.

Best regards,

Thomas
