Hi,everyone.
I would like to use the OpenFOAM function LUsolve, but I don't know how to use it. After studying the code in which LUsolve is used, it seems that, for example, if one wants to solve the simultaneous linear equation Ax=b, one can use the statement LUsolve(A,x), where b is added to x in such a way that it is transferred to the left side. I do not understand why b is added to x. The code for the viewfactor method I referred to is as follows Quote:
where: Cij = deltaij/Ej - (1/Ej - 1)Fij q = heat flux b = A eb - Ho and: eb = sigma*T^4 Ej = emissivity Aij = deltaij - Fij Fij = view factor matrix Can someone please tell me how to use LUsolve in detail? Thank you in advance. |
