Calculix B32R Element in DYNAMIC calculation

Postby Tianqi » Fri Mar 08, 2019 8:17 pm

There is a problem in CalculiX when using
B32R
element for
DYNAMIC
simulation. The ccx failed with errors shown in the following.

Code: Select all

Using up to 1 cpu(s) for the stress calculation.

*** Error in `ccx': free(): invalid pointer: 0x0000000002800c50 ***
======= Backtrace: =========
/lib/x86_64-linux-gnu/libc.so.6(+0x777e5)[0x7ff9355ac7e5]
/lib/x86_64-linux-gnu/libc.so.6(+0x8037a)[0x7ff9355b537a]
/lib/x86_64-linux-gnu/libc.so.6(cfree+0x4c)[0x7ff9355b953c]
When change the
B32R
element to
B32
element, it successes. Also, there are no errors in
steady state dynamic
and
modal dynamic
when using B32R element. As I found in the manual, for calculating section forces, the B32R element gives more accurate results than B32 element.
Is there anyone encounter the same problem when applying
B32R
element to the
DYNAMIC
analysis.
