Hello everyone

I'm in the process of trying to learn how to use OpenFOAM / dsmcfoam to use in my own project ( Gas injection into a cylinder at vacuum pressure ).

After following lots of tutorials online ( 12 hours straight yesterday! Ugh!) i have now got to the point where i have modified the 'Wedge15Ma5copy' tutorial study that is included with the software.

I have meshed my cylinder with SALOME and it shows in ParaView , although when I run the case it returns blank after a second or so.

As it is a fully enclosed volume (i.e no external boundary) I am not sure if I require the 'blocks'

I set up the cylinder as all wall and one inlet.

I have uploaded my case files here : Google Drive Link to zip file

View in ParaFoam ( before running) ( I know my axis is incorrect in terms of inlet direction, but I dont image this to be a problem for this piece ? )
