Hi,

Can anyone tell me what this error means in fluent 6.2??

Error: eval: unbound variable Error Object: porous?

How can I correct it?

Thanks

hi rekha,

Can you provide some more details about the error? It might help to get at the real problem.

From what I know, this is a numerical error with the solver. Being a little more technical, most variables that the solver uses are bound to some memory locations that holds the values used in the solution. For whatever reason, the solver can no longer associate the variable with a location.

Some things you might want to look out for: memory usage. Make sure your grid is within the memory of your computer.

Also, have you defined a porous condition and if so what settings have you used. Hope this is useful, Phil

I assume u get this error while initializing. It is probably because of incorrect boundary conditons.
