error in fluent
 
Hi,

Mine is a 3D geometry wherein I used tetrahedron cells to mesh the entire geometry. The mesh file is read in Fluent and suitable inputs were given. After clicking on "Initialise" it is showing " could'nt allocate fine level coefficient matrix". Kindly suggest me to overcome this error.

Thanks in advance

Re: error in fluent
 
As far as I know, this error can occur for example when trying to initialize a solution to a large mesh with the coupled implicit solver and your computer does not have enough memory to do that. If that is the case, changing the solver (to either coupled explicit or segregated) or using a less dense mesh, or even changing computer or amount of memory will help you.

Good luck!
