Hello

I took the solver icoFoam and put in a bunch of runtime.write() statements, to see which function calls modify which objects(U,phi,T,p etc).
The problem is when i run it values keep getting overwritten.

Is there a way to direct the outputs to a different directory apart from the default?

Thanks
Srinath

Hi Srinath

I haven't seen such possibilities, but you can always put in a "system"-call. It is not beautiful but it would work:

Something like system("mv $PATH/U $PATH/U_0"), etc. Of course you need to handle the string correctly as the above is purely illustrative.

Hope it is useful for you.

Hi everyone,

I have been trying to simulate the flow around a cylinder. I generated the mesh. When I run it, it was giving following error. Can anyone explain what is the reason?
