particleErosion cloudFunction in 2.1.x
 
Has anyone been able to get the particleErosion cloudFunction in the 2.1.x Lagrangian libraries to actually work?

if you want to test, through the following lines in the kinematicCloudProperties file in the hopper example

Code:

cloudFunctions
{
        particleErosion
        {
                p  2.6;
                K        2.6;
                n        1;
                patches ( walls );
        };
}

the model is initialised, but the field is always zero. I would expect particles hitting a wall would cause erosion. The only mention of the cloud functions, outside a mention on openfoam.org, that I found was in a bug report. Anyone else?

Always zero: when you look at the internal field in paraView or when you look at the file on disk (or alternatively looking only at the wall patch in PV)? In the first case I'd not be surprised if everything is 0. If in the 0 case everything is 0 you have a problem

The past days, i have tried doing erosion analyses in OpenFOAM using a copy-paste of "Cloud functions" you posted below. It does give me a non-zero field output at the end of the job.

Which wear model does this correspond to? Do you have access to any documentation on the wear model?

Thank you in advance.
