Hi cfd colleagues,
I'm using bicgstab method with ILU preconditioning to solve my linear systems on my CVFEM code. When I solved the lid driven cavity flow the code worked fine, but now that I'm solving an inflow outflow problem I'm getting this error: ??? Error using ==> ilu There is a pivot equal to zero. Consider decreasing the drop tolerance or consider using the 'udiag' option. I dropped the tolerance like MATLAB suggested without success... Any idea about this issue??? Thanks in advance..... |
