Hi there,
This is Julio. I am new to OpenFoam and CFD. I have a very basic question but I am having a hard time trying to fix it. I have a very basic space I want to analyze the temperature and air speed variations within. I have inlet boundaries and some other interior features. The problem occurs when generating the main boundary of the space the shape is similar to a semicircle but I simplified it with straight lines. However, when I run the OpenFOAM meshing it generates a mesh with very coarse edges and this gives me very strange results. I have marked in red how I think it should be to obtain more realistic results. Does anybody know why is this happening? which parameters should I modify to obtain a straight mesh? which is the right settings so all the inlets work as they should? which is the right boundary type for a AC system, inlet boundary or inlet flow-rate boundary? Thanks in advance. |

Hello Julio,
please upload a picture of your mesh and post your sHMDict. Why do you use straight lines and not just a semicircle? Where are your inlets and where are your outlets? What solver are you using? What boundary conditions are you using right now? Best regards, Vinz |
