Hi, all
I am simulating a fluid flow in a periodic cylinder pipe using OpenFOAM.
The 0/U and 0/p files are set as following:
0/U
inlet
{
type cyclic;
value uniform (0 0 0);
}
outlet
{
type cyclic;
value uniform (0 0 0);
}
wall
{
type fixedValue;
value uniform (0 0 0);
}
0/p
inlet
{
type fan;
patchType cyclic;
f List 1 (-0.0128);
value uniform 0;
}
outlet
{
type fan;
patchType cyclic;
f List 1 (-0.0128);
value uniform 0;
}
wall
{
type zeroGradient;
}
It works well.
But when I run the simulation in parallel, the pressure field and the velocity field become zero in the first time step.
Do you have any idea for the reason? Thanks in advance.
