How can I link Mass & Energy source terms through UDF with the FLUENT code for VOF multi phase model?

I got one really good paper on "Two phase modelling in ANSYS FLUENT", in which they have used UDF and linked them to Governing differential equations of VOF Model in ANSYS FLUENT. The Paper I have...

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...

Grigory Ermolaev

it is a classic Stefan flow or Stefan diffusion problem, you can find it textbooks on combustion or chemical technology

Somnath Rangrej

Sir actually I am looking for, how to model those phenomenon on ANSYS FLUENT, to visualize the different aspects of fluid flow.

Please check the paper which is on selective condensation.

"A numerical model for the fractional condensation of pyrolysis vapours"
