How do you make a set containing a cell? When I create a cell I can only select a surface.

I was wondering if there was a way to assign a cell a name much like what can be done with a surface. I’m trying to assign a body heat flux to a cell that I have partitioned and cannot physically see in CAE. If you cannot assign a cell a name is there away to deactivate cells on the outer...

I have been looking through the documentation for the theory i.e. the general PDE's, used to solve coupled thermal-mechanical problems. Thus far I have had no luck in locating this information and have only found information on coupled thermal-electrical analysis. Does anyone know if these...

How do you transpose the data to the new coordinate system? Thanks

If I have a cylinder shaped part, is ther a way of making ABAQUS show circumferential and radial stresses? Do i have to introduce a cylindrical coordintate system before running the job? Thanks

Here is another thread I started don't know if any of you would have experiance in this or not. http://www.eng-tips.com/viewthread.cfm?qid=277382&page=1 Thanks

I’m having trouble with my model not converging. It is a thermal-mechanical analysis with a contact condition in place between the two plate along with a heat flux. I know the convergence issue is tied to the contact constraint because it will run when it is suppressed. I have attached the .cae...

Partitioning it along the X and Y plane helped a lot, I was able to use a structured Hex-mesh. I was wondering how you knew to use that approach? I have only been using Abaqus since the beginning of the year and my experience is a little limited. I would like to know for future models. I am...

Rob, When you partitioned the model on the X and Y plane did you partition the cells in the models or the surfaces? I assume it’s the cells but just want to make sure. I know the seed size is a bit of an over kill but I'm trying to get mesh independence so I'm just taking it down to explore the...

Ohh I was actually using 0.0005 not 0.005. That was my mistake in the post. The .cae file should be 0.0005 unless I messed that up as well. Could you maybe look at with the 0.0005 seed value? I'll also look into the Hex mesh. Thanks for the help.

I have been having trouble getting two annular parts to mesh. I am trying to produce a mesh using tet- elements which will be used in a thermal-mechanical analysis. I can mesh the model when the seed size is large but when I lower it to around 0.005 the model will not mesh and I get an error...

What initial increment size did you use; I tried a few different ones and could never get it to converge. Also how many iterations did it take to converge? I am using a 3D model and non-symmetry because this model will be used for a show and tell for the higher ups and they tend to like pretty...

Forgot the file it is attachedhttp://files.engineering.com/getfile.aspx?folder=fc98b348-90b3-482b-9de6-1ffae31d9d04&file=Forum_Model.cae

I have attached a .cae with the model I have been trying to run. It is a fully coupled thermal mechanical analysis of two aluminum plates that are weld about their edges. There is a uniform temperature gradient across the thickness of both plates. The central area of the plates has an...

I have been having trouble with a thermal-stress model that will not converge. I believe my problem is somewhere in the contact interaction I have applied to the model called “internal contact.” The model will converge with a low density mesh with the contact interaction on but it will not...

I am having some trouble getting my fully coupled thermal stress model to converge with higher density meshes. I have lowered the increment size in the past to get it converge but now I get this error related to heat flux. There is zero HEAT FLUX everywhere in the model based on the default...

I have two aluminum plates that are the same dimensions which are laid directly on top of each other. I am trying to figure out a way to simulate a weld around the edges of the plates. I need to take the nodes located on the edges that are in connect between the plates and tie them together. I...

I am running a parametric study and I'm trying to figure out how I can run parallelization. Currently the study is only running on one processor core and it would be nice to run on multiple ones. I don't know if it should go in the .inp file or the .psf file. Any help would be appreciated. Thanks

That worked. Thanks

I'm am trying to run the example: Parametric study of a linear elastic pipeline under in-plane bending which is 1.1.3 in the abaqus example problems manual in the 6.9 documentation. The procedure I am using to run the file is as follows. I put all the .inp files and the .psf file in the same...
