Hi

I am trying to run a dynamic mesh problem in parallel (pimpleDyMFoam) (it runs perfectly fine in serial) but I get the following errors when trying to run in parallel:

Selecting dynamicFvMesh dynamicMotionSolverFvMesh
Selecting motion solver: velocityLaplacian
[2]

[2] --> FOAM FATAL IO ERROR:

decomposePar runs perfectly fine without any errors. My pointMotionU in the case/0/ directory looks like:

dimensions      [0 1 -1 0 0 0 0];

internalField   uniform (0 0 0);

boundaryField
{
    leftBoundary
    {
        type            zeroGradient;
    }

    rightBoundary
    {
        type            zeroGradient;
    }

    centerLine
    {
        type            symmetryPlane;
    }
	
	upperWall
	{
		type			dynPerCircle;
		circleRadius	0.01500;
		xCompInitialCenter	0.0;
		speed			0.00500;
		yCompFinalCenter	0.01900;
		value			uniform (0 0 0);
	}
	
	frontAndBack
	{	
		type empty;
	}
}

Thanks in advance

Hi,

Which files do you have in the "0" folder ?

regards,

Arthur

[Nadun19]

The <case>/0./ folder has p, U and pointMotionU files

[mojuss]

delete (or keep a copy) of the pointMotionU file. decompose your case and run the case in parallel.

[Nadun19]

The case doesn't run without the pointMotionU file, i.e. I get this error:
