Hi all,

I am new to OpenFOAM. I have installed OpenFOAM in windows. I am trying to run a steady state incompressible turbulent analysis of glycol through a chamber. I have created the mesh in SALOME and exported it as a .unv. I then used ideasunvtofoam to convert the mesh. When I go to run simplefoam I get the following error:

The file "p" is there so I am not sure why it is saying it cant find it. I edited the files with notepad in order to put the correct values in.

Hey! have you solved this issue? I also ran into the same error, but in my case, it is a T file. do you find any solution or thread to tackle this error ?

[hammerpe33]

JKY,

I have not found a solution. I had to move on to some other projects but I still need to figure this out. I need to finish this analysis in the coming month so I will be circling back to this soon. If you find anything out please let me know.
