<br>__________________________________________________ _<br><br>after i 3D mesh it and convering it using gmshToFoam, fixing the boundaries etc., loading the mesh using paraFoam, the inflow and walls apears great.<br>However, <b>there are no inside (volume) cells</b>.<br>
It seems that the msh file does not contain the "vol" cells.<br><br>what am i doing wrong ? im sure its a no brainer<br></span>
