I try to solve a shell - model by using SOL 106 to consider large displacements.
In general I am using three solutions:
1. is Sol 101
2. is Sol 103
3. is Sol 106
At my first attempt I have used linear elements. Therfore everything worked fine.
For my secound attempt I changed to quadratic elements. Therfore Sol 101 and 103 also finished without any problems, but at Sol 106 I got the following error message in f06-file:
*** SYSTEM FATAL MESSAGE 3007 (NLITER)
ILLEGAL INPUT TO SUBROUTINE NLINIT
Has anybody any idea of the meaning of this message and how to solve it?
PS: In the NASTRAN Error Message List I found the following information:
3007.0 ILLEGAL INPUT TO SUBROUTINE %1
Subroutine %1 has encountered data which it cannot process. This
error should not be caused by user input data, except as described
in the next paragraphs. A system or programming error is indicated.
Go directly to the subroutine listing or description to determine
the exact cause of the problems.
This message occurs in superelement analysis when restarting improperly.
The illegal input message is usually caused by a purged input file.
One example is if the subroutine is CALCV. A common cause of this
error is when attempting to perform a PARTN (or MERGE) on matrices
with null partitioning vectors, or attempting to perform UPARTN
(or UMERGE) on a matrix for which the original set is the same size
as the final set. In this case, the partitioning vector generated by
the program is null and this error is generated. In CALCV, if the DMAP
partition "hard-coded" and the set does not exist, you'll get this error.
For example, if a UPARTN module is using the Q-set, but the user hasn't
used any Q set entries, this error will be issued. One remedy is to
conditionally jump over the problem DMAP based on parameters such as
NOQSET, NORSET, etc.
This can also occur if inertia relief is not used properly in SOLs 91
or 101. Make sure that the rules stated in Chapter 9 for inertia
relief are followed.
This has also been observed in SOL 129 models with initially closed
GAPs that specify the ADAPT method on the TSTEPNL entry. It can be
avoided by specifying the AUTO method instead. See Error Report 3733
in section 17.4 of NX NASTRAN Reference Manual.
