Dear all,

Thank you in advance for your time reading this.

I am creating a CFD model of a Solar Chimney Power Plant where incident solar energy will heat the air within the geometry however unfortunately I am unable to create a mesh appropriate. My skewness value is far too large and despite my best efforts of altering sizes and inserting inflation I cannot lower my skewness value at all. So much so that when a calculation is run I get a suggestion to better my mesh and doing nothing results in a floating point error when calculations are run; I presume due to the poor quality of my mesh?

Please see attached my standard generation mesh with associated skewness graph. While changing to smaller cell sizes improves its rating a little it is still not of satisfactory levels.

Any help would be very very much appreciated as I am finding it quite difficult.

Ben
