I have created a scalar field of the wall shear stress on the floor of my device. I would like to calculate the total area where the WSS is in the range 0.5-1.5 Pascals. Is this possible. I know how to set the upper and lower limits of a scalar field but that doesn't tell me the area in that range.

That's an interesting challenge. I had to think about it for a sec.
1. Create a Derived Part > Threshold. 2. Set the Input Part to be the desired surface. 3. Set Scalar to Wall Shear Stress. 4. Set Scalar Range to desired interval. 5. Create a displayer and make sure it is the same shape as the clipped scalar plot you already made. 6. Create a Report > Sum and assign Input Part as your threshold, area as your scalar and then set units. 7. Right click the report, select run report. Let me know if that actually works for you, never tried it myself. |

My method is similar to that of MBdonCFD. After I create the threshold derived part, I create a surface integral report of a dimensionless unit field function that I created (definition: 1) on that derived part to get the area.
