Check your VPN software before you upgrade to Windows10 and some reports on ABAQUS’s compatibility with windows 10

I recently upgrade my laptop from Win8.1 to Win10. But the wireless and Ethernet won’t work immediately after upgrading. This sucks because it prevents you search solutions on this very computer! First I thought maybe it was the network drives too old but it’s not the case. Then I found it is related with the VPN software I used.

I am using a  Cisco VPN client distributed by my university. Somehow this software is prevent my Win10 upgrader from correctly setup the network when upgrading. On Microsoft website there is a post indicating Sonicwall Global VPN will also does the same thing (http[......]

How to switch between ABAQUS research and teaching license if your organization supports both, and some useful information on token consumption. Well, also a link to FREE student version ABAQUS.

Let’s assume that you are working in an organization that supports both teaching and research license. By some chance, you may encounter the problem of only got teaching license while you have been authorized to using research license but the IT support team fails or is delaying to switch it. It’s also not strange that this happens just days before a project due and you’ve still got a huge job to run.

If above is true, the following step may be the best way to solve your problem.

 

1.Find where your ABAQUS is installed, most of the case under C:\SIMULIA\ABAQUS\

2.Search for ab[......]

How to assign material orientations in ABAQUS?

Sometimes we need to deal with anisotropic materials and that naturally requires us to assign material orientations for our part.
To assign the material orientation other than default, we need to first specify a coordinate system(CSYS) based on the default one.

We can create a CSYS In Property module using this tool

Then, we need to choose CSYS type in the pop up window, in this example we choose Rectangular.

after that we need to input following information in order to describe the CSYS we are building.

1.coordinates of origin
2.point on the X axis
3.a point on X-Y plane[......]

How to determine the reaction force on a whole part in ABAQUS.

When we do our FEA study, there’s always some need to determine the total reaction force on some part. For example to obtain the maximum load of a round bar, we’ll surely need the reaction force on the load.

Or just like the following example, to determine an inserting force.

When we output the force, we normally choose output reaction force for any nodes that has been applied displacement boundary condition. But that will results getting groups of forces and require some data add up, sometimes when the geometry is irregular, the data process may ends up impossible. In this instruction,[......]

Solve code 1073741819 error when using standard analysis on ABAQUS 6.13

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[......]

How to link ABAQUS 6.13 with visual Studio 2012 and Intel Fortran Composer XE 2013

Update 5/6/2016:

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[......]

How to tie parts together in ABAQUS( in order to simulate welded and bolted parts).

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[......]

How to fix a Fedora crash mentioned “RUN fsck MANUALLY” nice and easy.

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.

So I Googled what’s on the screen, and found a webpage I can’t open seems describing the very same problem. However the cache is still usable, so I followed the simple steps easily fixed the problem. That actually reminds me of my early life of problem fixing on windows, I searched the in[......]
