Hi Syavash,

Try:

FieldConvert -m C0Projection test.xml test.fld test-C0Proj.fld

Thanks Guglielmo

It worked! 

However, the result is not satisfactory. I have a smooth velocity field but the wall shear stress exhibits discontinuities, likely due to C1 issue.

Could you suggest a remedy?

Dear All,

I am trying to extract the wall shear stress for a 2.5-D case using the wss module: 

FieldConvert -m wss:bnd=3 <mesh.xml> <session.xml> <time-averaged.fld> <time-averaged-wss.fld>

However, it is taking too much time to execute, more than 1 hour with no output.

I noticed another report on this issue in the mail archive, not sure if my case has the same problem.

I appreciate any help you can provide.
