Recently I encountered the code 1073741819, it’s an error happens when you use Intel Haswell processor to run a standard analysis.
Typically it’s a message like this:
Error in job ***: The executable standard.exe aborted with system error code 1073741819. Please check the .dat, .msg, and .sta files for error messages if the files exist. If there are no error messages and you cannot resolve the problem, please run the command “abaqus job=support information=support” to report and save your system information. Use the same command to run Abaqus that you used when the problem occurred. Plea[......]
For experienced folks just look at the bold font, it’s the cut the crap version.
Found an alternative way of linking those stuff when you can’t change the environment variable (happens when you don’t have admin access to your machine) and it’s actually much more easier than the old method, and potentially could apply to more software edition combinations. So I recommend readers to try this method first.
The gross idea is to use Fortran’s own way to setup the environment for Fortran in Abaqus.
After you install Visual studio and Fortran , you can find a shortcut for[......]
The question is from a guy asked for how to tie beam to a shell.
It’s basically the same thing as other TIE jobs.
1.Mesh two parts out and create new mesh part so you could operate whatever you want on the node or element.
(If you don’t know how to create new mesh parts, when you in the mesh module, choose :—mesh—create new mesh parts.)
When you mesh two individual part, whatever it’s shell- solid or solid-solid tie you wanted, you should make sure the TIE area are meshed the same or alike, so it will be easier to operate. However in this case, a beam connect to a shell on the[......]
Today I found I couldn’t upload file to our Linux server using SSH file transfer. I haven’t calculated anything on the server since last week and no one was touching it. I am confused. Anyway, after I reboot the machine, more serious problem occurred, at least looks very serious for a Linux newbie like me.
When we deal with multi-parts analysis, interaction between parts’ surfaces can greatly affect the simulation results. This example here I use is a shell model of a spring arc and two boards, when we pull the upper board upwards, the spring and board will touch each other and participate the stress distribute condition on the spring arc.
This is a compare of with & without contact interaction between board and spring. We can see not only distribution, the stress amplitude is changing.
This is an easy problem to notice since the spring are penetrating all through the board, and it[......]
When using FEM, it’s necessary to improve mesh quality in order to get accurate results.Now we are goanna learn how to refine mesh in ABAQUS and ANSYS on both 2D and 3D models.
2D model in ABQUS:
When we analysis a model, we can more or less predict where will the stress concentrate occurs therefore we are far more interest on the accuracy of these particular edges rather than other “cooler” part of the whole model.In 2D model, we express this interest on define local seeds beside global seed.
We add a local seeds control much detail than the global seeds on these edges we fond,[......]
