Mesh problem
 
1 Attachment(s)
Hi

My experiment is as follow,
I wanna simulate the flow around a cylinder at different Reynolds. So i use Salome I create a box for the boundary and introduce in the cylinder, I mesh it with netgen.
I do the checkMesh (everything is OK everywhere)

Or during the experiment when the flow touch the cylinder i the openfoam cannot converge...
So i think it's delta T, I compute the currant flow number. For more security i divide dt by 2.
And still not converge...
Where do you think there is an error?

- From salome with netgen ..
- pisoFoam is not the best solver for this kind of modeling?

I am aware about any advice.

Why don't you try with simpleFoam instead?
