ERROR 240: A triangle is too small or EPSENT is too large

Altair Forum User

I have meshed my wing and when I run the simulations for RCS I get the following error:

''ERROR 240: A triangle is too small or EPSENT is too large'' 

 

It worked for me when I had half wing but when I use full wing by mirroring it gives me error. I also tried making Union between components but still gives me error...

 

You can find my model attached herewith. Looking forward to some helpful advice.

Thank you!

Hi @Waqas Hayat,

 

I'm not at a computer where I can open the model but it sounds like a question answered in

This explains what EPSENT is and what could have caused the error.  Other tools that you can try include:

• Using some of the CAD fixing tools (usually helpful if you have an imported model); or
• Changing the model's bounding box size (this influences what the mesher sees as 'the same' point and might help to avoid an error)

I can try to open the model tomorrow but in the meantime maybe you can try a few things as well and let the forum know if anything (and what) helped!
