Therefore, I make the momentum matrix a tmp and call UEqn.clear(); at an opportune place in the code and drop the peak memory requirement by one complete assymetric matrix!

My understanding is that openfoam will construct an equation of the form Ax = b, solve it in some iterative way, and will stop iterating when the residual, |Ax

Hi everybody,

does anybody know how to create a mesh with PRIMS instead of HEX in "blocks" in blockMeshDict?
Is there any guide online?
Thanks

This model (see attached files) I created with a python script. With python you can do parametric modelling and it`s much easier than editing the blockMeshDict by hand. For 3D- boundary layer you can use salome (www.salome-platform.org)

I would like to inizialize a random velocity field with funkySetFields. Is it possible?

I've tried something like

{
field U;
expression "vector (0.005*rand(), 0.005*rand(), 0.005*rand())";
}

Do you think this should work?

Thanks in advance
