B vector in mhd module.
Hello
I need advice. I am using Fluent with MHD module to simulate my object. In MHD I can define value of vector B but only of external field. Now I need to calculate B of internal magnetic field (means: field made by current flowing by the fluid). Is any simple method to do this calculations. I am thinking some time over this problem. Do I have to write some kind of my own mhd module or I can use this in Fluent. I will appreciate your help. |
Hi Adam,
you can simply add any source terms to your N-S equations. I didn't use MHD module before, but it reasonably add appropriate source terms and properties to your solver; in other words, you can do any thing that this module do by your self without any restrictions with some UDFs. Bests, Amir |
I thought over what you have written. I suppose you mean to add sources to momentum equ. (in my case something like: JxB) and to energy equ. (in my case something like: (Jx^2 + Jy^2 + Jz^2)/conductance). My question is how to describe it in UDF - I mean how to put J (current density) which is "created" in MHD.

The problem is to define J equation. My fluid shape is a little bit irregular and I am not sure how to create model of current flow in it. What do you mean: "this vector is obtained from sth"? |

That means that I should turn off MHD module and write my own transport equations to solve it. I have never done it before so I have to read sth about UDSs and UDMs. Thanks a lot Amir.
Probably I will have further questions later. Best wishes, Adam |
