Is there a way to patch solid particles in the flow field without affecting the flow?

after getting the flow field we can use PBM module in fluent. once I activate the PBM module the velocity vectors become zero in the flow field.

When I change the primary phase from a single component to multicomponent in Fluent, does the flow field change or get modified?

does changing the species components change the steady flow field? how to sort out this problem

Loading PBM through fluent gives an error?

when I load PBM through fluent, in one of the tutorials it is mentioned that I need to save the case and data--> exit from fluent--->> load the case and data once again and patch the...

How to debug this error i am getting in Fluent " there must be more than 1 species on each phase"?

I am using multi-phase Eulerian granular model. I have activated the species model. I am trying to find layering on a solid surface from the bulk solution. I am having 2 phases ( 1 liquid phase +...

fatal error

When I tried to energy minimization my system, I got fatal error as below. Fatal error: Atomtype opls_116 not found Although I've already added this line: ; include water #include "oplsaa.ff/spc.itp" to [molecultype] directive in my topology.

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...

What is the characteristic length to determine the Reynolds number for the scattered turbulent fluid flow?

Dear all, I just saw this example in FB on the difference between laminar flow and turbulent flow. The flow from a pipe hits the sink and scattered. The flow from the pipe is characterized as...

What do you mean by predicting the growth rate ?

If you are using Ansys Fluent, you can define the growth rate as a constant or implement you own growth model using a User Define Function (UDF).
