ViewField() - Error "ComponentVoxel::ElectricField : Field is not available for interpolation"

Hello,

I wrote a macro to set a magnetic Field in a parallelepiped and do interpolation. I take the values of the magnetic field from a txt file. So, it is convenient to use the ComponentVoxel of garfield. The macro read well the values.

After I wanted to view the magnetic field but it prints the error message “ComponentVoxel::ElectricField : Field is not available for interpolation” many times and I don’t understand why. So, I cannot view the MagneticField.

Here is my code :

const unsigned int nx=13;
	const unsigned int ny=13;
	const unsigned int nz=251;
	const double xmin=-240;
	const double xmax=240;
	const double ymin=-240;
	const double ymax=240;
	const double zmin=-5000;
	const double zmax=5000;

	const std::string filename = "data_test.txt";
	const std::string format= "XYZ";
	ComponentVoxel *mesh=new ComponentVoxel();
	mesh->SetMesh(nx,ny,nz,xmin,xmax,ymin,ymax,zmin,zmax);
	mesh->LoadMagneticField(filename,format,1,1);
	mesh->EnableInterpolation(true);


	/*** Viewing the magnetic volume ***/
	TCanvas* c = new TCanvas()
	ViewField* meshView = new ViewField();
	meshView->SetCanvas(c);	
	meshView->SetComponent(mesh);
        meshView->SetPlane(0,0,1,0,0,0);
	meshView->SetArea(xmin, ymin, xmax, ymax);
	meshView->Plot();

And attached, you are the data_test.dat file.

Thank you in advance,
