Y+ value in porous zone while modelling flow through porous media ?

I am modelling a flow through porous media using ANSYS Fluent. The flow through porous media is assumed to be laminar. Shall I need to check y+ value in the porous zone also?

No title

In SST k omega model the flow is resolved up to the wall. For this the y+ =1. However, in some cases where the solution is converged and showing fairly good results, the y+ values...

Resistor definition in Piezoelectric bimorph with ANSYS workbench

Hello, good day! I am trying to simulate similar bimorph piezoelectric harvester with below commands. However, the output power doesn't change with resistor value. Please help to find the reason. ET,10,CIRCU94,0 !SET UP RESISTOR R,1,100000 !RESISTANCE VALUE TYPE,10 !SET ELEMENT TYPE E,1,2 !CREATE RESISTOR BETWEEN NODES 1 AND 2 Thanks in advance Regards,

Why are the velocities so high in my Boussinesq approximation Fluent simulation?

Hello, I have a mechanism where air rises due to convective flows. In this simulation, nothing is driving the air except this. I understand that the Boussinesq approximation only works for small...
