Improve CFD Accuracy with Correct Mesh Resolution It's important that your mesh near the wall is properly sized to ensure accurate simulation of the flowfield. This calculator computes the height of the first mesh cell off the wall required to achieve a desired Y+ using flat-plate boundary...
I would instead recommend using a y+ calculator (https://www.cfd-online.com/Tools/yplus.php) and enter the expected mean values of your transient simulation to get a reasonable estimate of the y+ value. Based on this value, you can change your grid appropriately to resolve the BL. Thank...
This two-dimensional steady-state heat conduction calculator provides the thermal resistance through the height axis of a solid slab, flat heat pipes, vapor chambers, or heat spreaders, including the thermal constriction resistance resulting from a heat source that is smaller than the slab, given un...
Next month, when students across Texas take an online state STAAR test, they will also {for the first time ever} see an *embedded* Desmos graphing calculator option in addition to a TI emulator. A “both-and” graphing calculator situation! Woot! Years back, we clunked our way through lo...

Y-plus-Calculator Y+ is a dimensionless parameter in fluid dynamics, defined as the dimensionless distance from the wall, generally used to express height relative to the viscous sub-layer near the wall. For properly modeling turbulent viscous flows in the near-wall region using CFD, it is ...
