Hello,
I met a contact problem in my modeling. Basically I have a thin-walled container (modeled as rigid solid), within which I have a soft gel-like material in contact. Loading condition is to sudden shake the container (and thus the gel inside due to contact forces). Because the gel has a...
Hi,
From a natural frequency extraction procedure, there's also report on "participation factors". Could someone give me a hint what this is, and possibly point me to some reading materials? Thanks very much,
Sean

Hello,
I took my vibration courses but I didn't know about the "participation factors" in a "natural frequency" extraction, e.g., from finite element analysis. Could someone point me to some reading materials on regard of this? I tried to google for answers, but not satisfied with what I...
Hi,
I am using variable mass scaling, "below min" option in my explicit dynamic simulation. As I observed from the .sta file, the percentage change of the mass is always increasing. My understanding is that after every, say 100 increments, abaqus computes the mass scaling for some of the...
Hi,
My model is a rigid body container (a thin wall) with deformable body inside. Running explicit, I frequenty have the overclosure problem. Abaqus tried to adjust the nodes cooridinates on the slave surface (the deformable body surface), but still there were unresolved initial overclosure...
Hi,
I know in abaqus website that the supported Sun Solaris platform is Solaris 8. Could anyone tell me if Solaris 9 is "accidentally" supported as well (I mean, you can still somehow install it, and it works)? Of, if Abaqus is planning to support Solaris 9 as well? Thanks a lot!
Hello,
Could someone explain to me how I should report values (e.g., maxPrincipal nominal strain values) for a particular element? I noticed that for C3D10M element, there are 4 integration points, and each has a certain value. How do people normally report? Average across these 4 values...
Hello,
Could someone tell me if abaqus node/element numbering could affect abaqus simulation efficiency, and why? For example, one part has numbers from 1 to 100, and a second part has numbers from 1 million to 1 million + 1000. Would this affect abaqus efficiency?
Also, in Patran, there's...
Hi,
I am using Patran to auto mesh 4 parts that are in contact with each other. They have some coincidental surfaces, patran detected that, and I chose to create duplicate surfaces. I assigned mesh seed on the surfaces by part, and because some surfaces are coincidental, if I assign mesh seed...

Hi,
I am running abaqus/explicit, with deformable body confined within a rigid surface formed by shell elements. After running and viewed from CAE, I can see that the deformable material goes outside the shell surface during the dynamic event. But how could this happen? Initially the...
Hi,
I have a question on regard of initial rotating velocity to specify before the STEP keyword. Abaqus supports both:
INITIAL CONDITIONS, TYPE=ROTATING VELOCITY,
and
INITIAL CONDITIONS, TYPE=VELOCITY.
For my problem, what's the difference between using these two options? If for the...
Hello,
I am using Patran 2004 to do post-processing. When I use:
Read results-> result entities -> attach,
and select one of the .odb file from Abaqus explicit, it repeatedly tells the following error:
cannot load dynamic library /local/msc/patran2004/lib/libabaqusdra.so ld.so.:/ ...

Hi,
In my input file, I clearly defined several node/elem sets. But when I tried to use Python to retrieve the node/elem sets, using:
odb.rootAssembly.nodeSets.keys()
I don't get anything -- no node sets that were defined in input file showed up. What is the reason? Thanks!
In addition...
Hi,
Could someone tell me if there's a type of 3D element in abaqus, that only supports tension, but not compression, i.e., if the element is experiencing compression, the stiffness becomes zero? Thanks a lot!
Hi,
I am running abaqus cae on a unix workstation, through my PC (installed with Exceed). But I am unable to run it, and it reported the following error: (I have DISPLAY property properly set up). Can someone tell me what is going on? Thanks a lot!
