DFN geometry vs domain extent

3DEC
1

Hi,
3DEC7.00.133 crushes when the script below is executed.
If I uncomment the 3rd line to change “x1extent”, then it works.
Why is that ?

model new
[x1extent = (84. - 10.) - 45.]
; [x1extent = -150.]
[x2extent = 250.]
[y1extent = -300.]
[y2extent = 250.]
[z1extent = -100.]
[z2extent = 150.]

model domain extent [x1extent] [x2extent] [y1extent] [y2extent] [z1extent] [z2extent]

It looks like a bug. When you make DFNs this way, it assumes the center is close to 0,0,0. We’ll make a fix ASAP. What version are you using?

Thanks for your reply !
We tried 2 versions 7.00.133 and 146 and got the same crash.
By the way, we often have “roll back” problem while installing a minor version. Is there any tips to fix this ?

The rollback is usually related to some conflict with the security key drivers. Try following the instructions under point 3 at this link: https://www.itascainternational.com/software/faqs/how-can-i-resolve-software-license-related-errors
