Issue in viscousDrag post processing

[vanchisen]

Dear NekRS,

I want to calculate the viscous force in flow past a circular cylinder.
I have used postProcessing::viscousDrag() following /examples/ ktauChannel/ ci.inc..
However, I get stuck at this snipped of the code, in particular, NekRS stop at o_drag.CopyTo(drag).
So I wonder if any one could please take a look at my mesh or input parameters ? in case they not compatible with the postProcessing functionality ?
The Gmsh *.geo, input *.par *.udf *.usr, *.oudf are located in following link,

Best Wishes,
Zhicheng Wang

Hi, I find a way to work around this issue, which is commenting out the @barrier in line 60 in /kernels/postProcessing/drag.okl
Not sure if it gives me correct value.

Best,

This seems to be the correct fix.
