For all the problem of intiating contact first and then applying the full load. I'll recommend using *CONTACT CONTROLS, AUTOMATIC TOLERANCES in the first step & intiating contact with displacements. Then in the second step, use *CONTACT CONTROLS, RESET.

Soory for my lack of information, brad. I'ld rather stop talkin' about nastran because i'm not working with it no more ...

Considering your problem, I want to had a question : do you need nastran only analyze or also to share models with others. In the first solution, each code will be OK and as a pre/post i'll say you FEMAP is quite simple. In the second option, you ll have to buy a MSC solution (MSC-Nastran or...

I think it is also possible to add temperature restraint via including an ascii file (.fil) in your input data (.inp).

I agree with brad, *TEMPERATURE is applying to nodes with Abaqus/Standard (or sometimes with an *BOUNDARY if you use elements with a #11 DOF). Can precise if you are using Standard or Abaqus/CAE ?

I am sure that Abaqus is working with LSF. I spent most of my day coding the submission of Abaqus jobs via LSF. I noticed new options for submission via LSF or other queing software in 6.3 Version. New options in the run_mode line have been added in the abaqus_v6.env file(=...

The problem is that in my curent version of Abaqus (6.3-1) and in the other one in an use (6.2-7) : those are differences (only a little : less than 5%) but there is a difference - and my fellows disturb me with such a small difference 8-( ). I cannot use a modelling strategy with only using...

I'm seeking for any piece of information about the accuracy of both elements in abaqus static analysis. Especially : Which one is "better" (in terms of Stress and Plastic Strain) in a simple analysis i-e without contact ? Which one is "better" (in terms of Stress and Plastic...

Is anybody using (or has anybody used) the Zencrack code and the modulus associated with Abaqus ? Have anybody informations about : - the results it gives (if they are good or not) - if it's easy to use - if it's easy to install on a big computer-system ?

I'll reply with my own university lectures souvenirs : - U can assume that a thin shell is thin when thickness is 1/20 of length (i was learned 1/10 but i'ld rather use 1/20). This notion is geometric and not linked to your element size. - U must check that your problem is linear i-e : - a...

I ll try to answer in child like terms ... This is only a convention to get infos about your analysis but it s also a way to calculate the Modal Mass Participations (automatically computed since Nastran 2001 - but sometimes bugged) which can be a very simple way to determine which modal analysis...

Very old question but very simple response so i answer ... Syntaxcheck is a run mode (just like analysis, datacheck & continue). Using Syntaxcheck will verify your syntax and generate a .dat without doing memory estimations. It will not get license tokens (if so, contact your reseller to...

As corus said, using a stabilize option can be a correct solution but take care using this option because it can also help convergence of an analysis by giving unphysical results. The way of solving problems is to check all infos in your .msg file : first by running an analysis with...
