hello all, I have a model which is working fine in 2.13 (windows) or 2.16 (Linux). But In 2.19 or 2.20, It gives me warning and an error. I checked the source of that error and there is no difference between the version. The error: "\*_ERROR in gen3dnor: size of estimated_ - ``` shell normal in node 112 element 13547* ``` - ``` is smaller than 1.e-10*" ``` The Warnings: "\*\*WARNING reading _NSET/ELSET: value XXXX_ - ``` in set BACK > nk*" ``` I checked also the geometry and it’s ok (see image, the X is the node 112). Any idea? Thanks Max PS: I don’t know how to attach the model ![mesh](https://global.discourse-cdn.com/free1/uploads/calculix/original/2X/d/d2bf05d38115e749d444c9ac42f9d463b6838d18.png) ---

I think I found the issue… I have several grid points where 1 coordinate is xxxe-10. putting them on 0 lets my computation run in recent version. I still don’t know why it runs in lower versions. Thanks all ---

Yep, I think that is related to this: > > > Fixes issue https://github.com/Dhondtguido/CalculiX/issues/29 ---

Thanks, Do you know in which version it’s solved? 2.21? ---

Could it be too many digits (23) in this number?: _-1.8118839761882555E-10_ CCX has strict limits on length of fields which I can’t quite find at the moment, but that seems weirdly longer than usual. I changed it to: _-1.81188397618825E-10_ and it solved in CCX 2.21.
