Hello Thomas,
I, too, have been a FEMAP user for many years and mostly use Advanced Nonlinear Modules 601/701, which are part of the ADINA program. I was dismayed to learn that solutions 601/701 will stop being supported by Siemens, and will be disabled in NX NASTRAN starting July 2020. I had...
In the May/June 2011 issue of Rotoworld magazine there was an article discussing proposed updates to AS/NZS4766:2006 for polyethylene storage tanks. I have not been able to discover if any of those proposals regarding underground tanks have been adopted. They seem very conservative to me...
Hello forum members,
I use FEMAP and NX Nastran Advanced NonLinear (Sol 601).
I have been experimenting with large displacement and large strain options and see in the documentation thst various measures for stress and strain are used in the element formulations (Green-LaGrange, 2nd...
Hello Rob,
You will have to do a dynamic analysis with the velocity from the drop as an initial condition.
I work on dynamic problems using Advanced Nonlinear modules (solutions 601 and 701, ADINA modules) because
I have contact surfaces, but I think you can solve your problem with the...
Hello 724napier,
There is an excellent Master's Thesis by Justin Paul McGrath that you should be able
to find if you Google
"Analysis of Axial Load Distribution in a Spline Coupling".
It has additional references cited also.
I would attach a PDF but I am uneasy about distributing copyrighted...
Hello 724napier,
I have recently been analyzing hub-shaft torque transmission: interface pressure varies along shaft length
which precludes 2D analysis. I could dig out some references if you care to look this up.

Hello forum members,
I am running NX Nastran with Femap but I also have a NE Nastran license. The troublesome file
also gave the Windows error when I tried solving the model using NE Nastran. It crashed the same way:
immediately after clicking the "Analyze" button, before either NX Nastran or...
Hello forum members,
FEMAP 11.1 occasionally gives Windows error and closes when analysis (SOL 101) is started.
This has happened to me on two different machines, one running Windows 7, the other XP, both 64 bit,
with the same file. I then exported the file as a FEMAP neutral, Version 11.0.1...
Hello forum members,
I wanted to follow up my question. I submitted the problem to Siemens GTAC support and received a prompt reply:
"The NX Nastran 8.5 Quick Reference Guide bulk data entry for CQUAD4 lists a remark as follows:
Remarks related to SOLs 601 and 701:
1.ZOFFS is ignored."
I...
Hello Blas,
Thank you for the reply. I had read the contact information from the Modeling Guide before posting
my question and posted only after I could not get results that allowed for shell thickness and for
shell offset from the meshing surface. I had run analyses using linear contact that...
Hello forum members,
I have been running test cases using shell-to-shell contacts where the shells are off-set from the
contact surface. The NX linear contact solution 101 behaves as I expect: it will compensate for shell thickness
and also for the shell offset using the Z-offset setting...
I am performing FEA on an assembly that includes rotomoldings with inserts. I have found some data
for pull out forces for injection molded inserts but not for rotomolded parts. I am thinking of using the injection molded data reduced by a fairly large amount to compensate for different...
Hello Blas,
Thank you for the quick and helpful reply.
I also want to thank you for all the information you have supplied in this forum. I have learned much from you and always look forward to studying your replies.
Best regards
Jerzy
Hello forum members,
I'm considering buying a new workstation. I use FEMAP and NX Nastran and often run non-linear Solution 106
problems. I was looking at the Dell 7600 with 8-core processors. (I currently use 4-cores.)
Will NX Nastran use the 8 cores? I would probably get 64 Gigs of RAM...
