I want to use MHD model in my work but there is some confusion in using it. so, plz anyone tells me the step by step process of using it. I am going to use B=3 Tesla.

I have attached the pics of the model and also some others pics in which conditions are applied.

The link is not working

however for MHD module there is a discription in Fluent appendix

also you can couple fluent-maxell in workbench

1. First, create the boundaries and initialise the CFD analysis.
2. Use the adopt option to select the mesh area where u would like to apply the magnetic field.
3. The using MHD module initialise the MHD solver and apply the magnetic field with certain value by selecting the adopted mesh area.
4. Then solve the analysis.

Floating point exception error occurred when I run the calculations

If you follow the methods as I said u won't get any error. since its straightforward analysis.
It would be more clear if u attach the figures of ur analysis.

The reason for this error would be due to solution divergence.
I think you are applying the field to the entire domain. Try to create an entry length to the flow till it gets fully developed and apply the magnetic field at the developed region. That would work I guess.

I have tried this. But it again gives the same error.

These images are your first analysis. What changes did for new analysis?

I want to apply magnetic field from the lower side.
I follow the steps you have told.
Floating point error comes when I use MHD model.

First, tell me you used MHD model or not.
if yes then for what kind of work.

I did the analysis for MR fluid flow under magnetic field.
Bye!!!!

after your simulations have you write any paper

if i read that paper i think it may help me

I think this field should be used in all sections. Calculate the current input length until it grows and use the local magnetic field. It must have happened.

Magnetohydrodynamics (MHD; likewise magneto-liquid elements or hydromagnetics) is the investigation of the attractive properties and conduct of electrically leading liquids. The field of MHD was started by Hannes Alfvén, for which he got the Nobel Prize in Physics in 1970.
