FAQ: How do I avoid Left-Handed faces in Fluent?

Question

How do I avoid Left-Handed faces in Fluent?

Answer

You need to make Harpoon export double precision files. In the export preferences, change "single" to "double" for Export precision. This must be done before creating a mesh.

You will also need to run Fluent in double precision

Left-handed faces often occur when two dimensions are large compared to the third. Modelling cities and landscapes can produce this problem in single precision.
