Do successfully worked MHD module examples exist?

Peterpanza · December 10, 2012, 02:05

I tried to simulate the plasma arc welding process, I found MHD module iperfectly suits my need, but haven't worked out anything yet, all the variables in user defined memory are zeroes.

I would be very very grateful if anyone can share a successfully worked MHD module example

hi friends
I have the same problem , do you solve it ?

yeah,i had ,or i should say I hadn't
cause it just can not solve that kind of problem.

Now I am trying to solve it in old way with UDF and UDS,luckily,it is a 2-D module.

well, I mean i need it to work in this way:
put a current in the middle, and it generates a magnetic field,then put the Lorenzo force in the momentum equations as source term.
Maybe it can do that, but I failed to discover how

Did you use VOF model together?

Sorry pal,i dont need VOF to solve my problem, it is only a single phase problem

hi friends
I think I can use MHD in my model but I dont Know about Accuracy of it.

Do you have induced magnetic field in your model?

yes , I induce magnetic field in my model and it worked .

Do you mean you have a existing current,which is intended to induce a magnetic field?
May I know your model in detail?

No , I only have magnetic field . fluent cant model a current to induce a magnetic field .
