Hi all
always the simple things that trip you up !!!
I wonder if someone could guide me out of the woods ! I am running a case ( a simple split pipe ) The problem is its not writing ( recording ) and pressures
I get zero pressures through out the pipe.
I searched this forum and downloaded a similar case, compared all the cards and for the life of me I cant figure it out . I have courant numbers less than 1 , pressures where I think they should be , the case runs through without a warning
I have tried differing combinations ,,,all to no avail.
Can some kind soul check my input cards, or run the case for me to see where I have made the mistake ( its usually me !!!)

I drew the pipe , exported as a STEP file, Meshed it in Salome exported that as a UNV file the used ideasUNVTOFoam to finish it off, Check mesh looks ok.

finally I did FoamToVTK then paraFoam to look at ther finished files , all seemed to work ok, but with no pressures ..... and I should have some!!!!

Kind regards

Stephen
