undefined value in linsolv error

Hi,

im trying to run some 3d simulations, convection and diffusion through a cylinder surrounded by 2 anulusses. I am able to solve it with a direct solver (SPOOLES) but have to use a coarse mesh and hence a rather rough solution. I am restricted by memory for higher resolution meshes. If i try with any of the other non-direct solvers it throws up an error such as the one below:

Exception:
com.femlab.jni.FlNativeException: Undefined value found Linsolv
Messages:
Undefined value found Linsolv

Stack trace:
at lssor.cpp, row 863, (NaN_or_Inf_found_when_solving_linear_system_using_SOR)
at com.femlab.solver.FlSolver.femAdaption(Native Method)
at com.femlab.solver.FemAdaption.run(Unknown Source)
at com.femlab.server.FlRunner.run(Unknown Source)
at com.femlab.util.i.run(Unknown Source)
at com.femlab.util.aa.run(Unknown Source)

I dont know why this is happening... can anyone shed some light on this?

thanks,
Adam
