Hello,
I am trying to find information about whether music wire loses its tension over time. The diameter will be ~.030" and tension would not be terribly large, similar to what is used when they are actually in a piano (~50-75lb total force). But because of the application, some vibe and...
I am trying to write a script that creates some XY data from node sets in an odb. Using the rpy file I came up with the script below. But when I try to run it I am getting an error that the name "COMPONENT" doesn't exist. As far as I can tell, from both the rpy file and the scripting section of...
This seems like an easy problem but for some reason I have a mental block.
I am trying to model the change in a preloaded assembly as a function of temperature.
The basic situation is this:
A threaded retaining ring is torqued down to get a predefined preload, at room temperature. Then the...
Does anyone know if there is a script command (python) that will get the path of the currently open cae file? I know the one to get the current working directory but this isn't necessarily the place that the cae file is open.
Thanks,

Hello,
First off, I am new to modeling vibration/dynamics in Abaqus so most likely there are some basic errors that I am making. I am trying to set up an analysis that includes setting a preload on a series of optics and then look at how that preloaded system reacts to a frequency sweep. This...
I am trying to run a coupled temp-displacement model in 2019 standard (i.e. not explicit) and I am getting an error saying that the 'sim' file cannot be opened. The specific error is: "SIM database file cannot be opened - No such file: C:\Abaqus Work...
While I am not terribly familiar with Random Analysis I think I understand enough to start doing some basic random analysis in Abaqus.
Since I am not too experienced with this I figured I'd ask here before bringing this up to the customer.
I have an example customer requirement of:
Random...
I am getting an error that I've never seen before and can't find any info about it in the help or on the web so I am hoping that someone can point me to the problem. The error is
"***ERROR: System error in std_contactnodehash". It happens just after the step constraint checks ("COLLECTING STEP...
I am working on an application that requires an optic system that is sealed. The system in looking at diesel exhaust and can reach a temperature of 500 degrees C. Ideally this sealant would be both an adhesive (holding the lens in place) and seal, like an RTV would do at lower temperatures...
I am working on a project where a housing needs to withstand the diesel exhaust environment. The main hurdle is the temperature (~500 degrees C) because the housing is somewhat isolated from the gaseous part of the environment. I've looked around and found that the most common materials are...
I am running a simulation of a viscoelastic material with TRS behavior in Abaqus standard. I am starting to think that the calculated viscosity vs. temperature is not correct so I want to check it at some (any) interval. Does anyone know if there is an 'easy' way to have Abaqus output the...
When you input a temperature dependent thermal expansion coefficient does Abaqus interpolate the coefficient for temperatures in between those that you define or are they considered constant until the next temperature you define comes up?
I've tried searching in the help pages but I couldn't...
Does anyone know of a site, book, or paper that gives a basic method of determining the proper element to use in common applications. For instance: some basic criteria such as when I can normally use linear elements and when I should consider going to higher order elements and when should I...
I have a bunch of test data for a viscoelastic material and I would like to distill this down to a viscoelastic model in Abaqus without using a custom material subroutine. And quite frankly I am not sure where to start.
Data I have:
TCE vs Temp
Viscosity vs Temp
Cp vs Temp
For now I can ignore...
I work with optical designers and as one of the checks for expected performance they perform a monte carlo simulation of the system they are designing.
Normally these systems have a fair number of variables that are being simulated (usually ~100) simultaneously. Each one is changed, within...
I am still a relative beginner with Abaqus so I apologize if this is a dumb question.
I am trying to model a chunk of glass that is heated up to a temperature above its transition temperature, but less than the melting temperature. So it should act like a viscoelastic material at these high...
I am just learning Abaqus (both main program and scripting) so I will apologize ahead of time if this is a dumb question.
I have written the script below to create an axisymmetric part that I will then use Abaqus to analyze. But when it gets to the last line of the code I get the error "Shell...
We are just about to purchase a seat of Abaqus and the sys req say that we need Visual C++ 2005. I can't find any company that I have dealt with before, and hence trust, that is still selling this. Everyone is selling 2008.
Does anyone know if this will work? I have read that the new Visual...
I am currently working for a company that, despite my urging, doesn't see a need for in-house FEA.
I think it is a good skill to have and the piece of mind that it would provide if the FEA results were in line with hand calculation would be nice too.
So I am thinking of purchasing my own copy...
