Hey guys,

I started to work with ICEM CFD and FLUENT and I got a small problem.

I created a rectangular surface (2D model) in ICEM, created a simple mesh and wrote an output file for Fluent. To this point everything worked well.

I opened Fluent and tried to open the file but then the following text appears and the only thing left of my mesh is a single straight line.

What did I do wrong? Its probably a stupid question but I would be happy about help.

Info: The mesh contains elements that are invalid or of poor quality.

A different numerical scheme will be applied to these elements,
which may affect the quality of the solution. It is recommended
that you consider removing the invalid and poor quality elements
in the mesh.

For more information on the invalid and poor quality elements,
please use the following TUI commands:

/mesh/check
/mesh/repair-improve/report-poor-elements.
Warning: non-positive volumes exist.

There are many reasons.

1. Association problem

2. Mesh is not in X Y plane

3. There is some element with high skewness

Some pics would help to identify problem area.
