Hello I am new to star ccm, and I have been trying to simulate the velocity and heat transfer properties of super critical co2 through a micro impingement jet. Whenever I run it, my max velocities are very high which doesnít conform to my calculation. I believe the problem is with my mesh but it looks fine to me although I might be wrong as this is my first experience on numerical simulation. I double checked the physics and it looks correct. I really donít know where I am getting it wrong.

Also included in the geometry is a heater of 100nm thickness. Iím having problem meshing that as the thickness is very small. How can I go about all these.? Thanks
