Hi, I am using a number of REC bodies in my geometry, which I have entirely constructed with the Geometry editor in FLAIR (I have not modified the numerical values manually). I systematically get an abort for geometry errors, claiming that the axes are not perpendicular.

TO 1ST SEMIAXIS Run stopped! STOP REC HEIGHT NOT PERP. TO 1ST SEMIAXIS Is there a numerical issue when producing REC bodies in FLAIR … or am I missing something ?

Dear Markus, thank you for reporting. We are currently investigating the issue. Cheers, David ---

Hi Markus, flair is using 15digits of precision for the bodies, however since some contain a minus sign and a leading zero it ends with 13 significant in some of your REC and then fluka complains. As a temporary remedy, you can use the **Orthogonal** button ![image](https://fluka-forum.web.cern.ch/uploads/default/original/1X/7958a727c3a20d20f73dedf362a87bb81dec1e08.png) Select all bodies or only the problematic ones, the **Body** context menu will appear and click the **Orthogonal** which normally should fix the issue. I will increase the significant precision of the bodies for the next release. ---

Many thanks ! (Another button’s function clarified 🙂 ) ---
