negative mesh elements in turbogrid

sarath_b · December 16, 2014, 00:03

Hello everyone,
i have done meshing for axial turbine rotror using 'traditional topology with control points'. it is showing mesh elements with negative volumes. i have tried adjusting control points but in vain. some of the members in previous threads suggested to use 'template' button, which i didnt find in my turogrid . Please suggest me how can I avoid formation of negative volume mesh elements.
Thanks in advance.

Hi Sohaib,

The original question did not have a lot of useful information in it. And the original poster did not use a suggested subforum.

Using subforums for software specific questions significantly increases the chance that a knowledgeable member reads it and might be able to answer.

Therefore, i suggest you to open a new thread in the ansys meshing subforum and describe your problem in detail, ideally with pictures, what you have tried to solve the problem and what other symptoms you have found (error messages, locations of invalid elements).
In most subforums there is also a sticky post with some information on how to ask good questions (to increase the chance to motivate someone to answer).

Best regards,
Sebastian
