Not all data is transferred from Fluent as some is calculated as needed. Have a look in Fluent, and you may need to add it to the data export. n

Thank you, below is all the data i can export from fluent, please is the shear rate is the strain rate or it caclualted by something else?nBest Regards,nTareqnnn

[Amine Ben Hadj Ali]

Do use CDAT Export and select strain rate or better to do post-processing in Fluent. Shear Rate is the Strain Rate. n
