THE PROBLEM MAY BE SIMPLE, BUT I COULDN'T FIGURE IT OUT.




Create mesh for time = 0

Reading thermodynamicProperties

Reading transportProperties

Reading field p

Reading field T

Calculating field e from T

Reading field U

Reading/calculating face flux field phi


Starting time loop

Time = 1e-05

Courant Number mean: 0 max: -0

empty b.c. can only be used for 1D or 2D geometry. In simple terms your mesh has be createable by extrusion. Front and back then can be empty but it is up to you to guarantee no flow/pressure gradient in that direction. See the lid-driven tutorial as an example.

Thanks, It really helped and i had fixed the problem
