@dhondt Dear Dr Dhondt,
since the newest release of CalculiX (2.18) brought improvements to the user beam element, I checked whether the two recently discovered bugs are still present in this version or not. Apparently, this problem is fixed: Doubt about userbeam.inp (U1) from ccx test
But the one described in the current thread still occurs. I thought that both issues have the same cause but it seems that it’s not the case. Is there a chance that this bug discussed here will be fixed too? User beam elements offer large flexibility to users and it would be great to have them working reliably.
Best regards,
Calc_em
