I'm new to Openfoam, but i have been using other CFD tools like simscale and simflow, Altair And many. I was trying to run a rhoSimpleFoam for an airfoil. But I am getting some error.



I would Also like to know how could i use snappyHexMesh For this.


Error I'm getting.

It says cannot find temperature boundary field , check Temperature boundary in 0/T.

thats sweet, i am gonna cry, lol, joking

obviously, you did create a mesh with blockMesh and named your boundary 'boundaries', which occurs in the error message.

--> FOAM FATAL IO ERROR:
Cannot find patchField entry for boundaries

file: /mnt/e/SC_2__0714/my_airfoil/0/T/boundaryField from line 24 to line 31.

openfoam tells you that it can not find the entries in the 0-directory for the file T, which is temperature. so basically, you did not adjust the file after creating your mesh.


if you don't know how to use OF you should check this out:
