Why ansys fluent Strain Rate gave me different result then using expression

01 January 1970 1 7K Report

Hello everyone, I am currently using ANSYS Fluent 2022R1. The XY plot and the strain rate contour I obtained from Fluent are different than when I used the expression (dV/dx + dU/dy).

Hussein Farroukh

It seems like you're facing a discrepancy between the strain rate contour obtained directly from Fluent and the one calculated using the expression (dV/dx + dU/dy). This could be due to various reasons, and troubleshooting such issues often involves checking several aspects of your simulation setup and post-processing. For example, the quality of mesh, the convergence study, and the good application of BC. Vibgyor Tash
