Hello,

I would like to calculate the area and volume of the solid of revolution obtained by revolving a sketch. I have used the query tool (mass properties) to get such values. The volume is OK but the area is equal to zero. How can this be possible? This is the warning I get from abaqus:

"Warnings: Some mass properties could not be computed due to the following issues detected while querying the selected region(s) - zero thickness, zero material density, missing section definition."

Hi All,

I was wondering if anyone tell me that it is possible to define cohesive surface between some parts that have complex shapes for example just by their sets?

thank you, 

I have written a python script to extract stresse values on a path, and it worked well, except one thing: for each point I got tow results. For instance, I got (0,-111) and below (0,11) and a huge difference between the ttwo values. the result is like a fluctuation. Could any one has an idea. many thanks

Hi All

one of the measures of the strain for forming processes is PEEQ , but I would like to know what is its application , specially in industrial applications like forming, should we compare it to anything ?

I am analysing Masonry infill frame using 3 loading steps in ABAQUS. The first step is Gravity load followed by In-plane loading and then by out-of-plane loading. I have to run multiple analyses in which only the time period of step -2 (in-plane loading step) changes. Every time I run the analysis the gravity step also has to be carried out.

Hello everybody,

I'm currently facing an issue on ABAQUS script and i hope some of you might help me on it.

I'm trying to access Element Sets from abaqus scripting interface, the different element sets of my model were defined on the .cae file.

The problem is the following: when i'm on the GUI i can display my element sets without any issues, but when i'm triyng to find my element sets on the scripting interface (using :

print openOdb(....odb).rootAssembly.elementSets)

they are not appearing (only 'ALL ELEMENTS' is available).

Hello,

Discretising geometries with a brick (voxel) mesh of constant element size is very simple and quick.  However, sometimes there are locally small features which would benefit from a more refined discretisation... In my case, the geometry (a textile reinforcement) is complex and tet meshes get very large very quickly – and are slow to generate. Hence, bricks are a simple way forward.

Here are some geometry examples: http://texgen.sourceforge.net/index.php/Main_Page

hi

I need help in using an initial stress field ( thermal residual stresses) in a new mechanical analysis.

I have tried two different methods, which give me two different solutions.

The first:

Hello,

I have to perform a thermo-mechanical simulation in Ansys WB and I have to provide the cte of a material.

I have few experience with thermo-mechanical simulation.

I have got a document with the material properties of this material; there I have the Tg (glass transition temperature)

and two coefficients: cte1 (below Tg) and cte2 (above Tg).

-->  How should I calculate the CTE for a temperature range (e.g. -50 < Tg < 300) ?   <---
