Ansys is capable of this type of problem. However there are a few issues that the user has to verify/check to get convergence. - contact stiffness - mesh size - time step/load increments. Ask yourself, is this problem non-linear? Will the material encounter plastic deformation? If so you...

oops, I do not think the attachment uploaded. here is the link to the SOLSH190 discussion http://www.ansys.com/events/proceedings/2006/PAPERS/22.pdf ____________ JohnyGluebag

See attached PDF, discusses the use and performance of the SOLSH190 element. Ansys 12 allows you to layer the SOLSH190, so you can get 3 elements thick on a plate if needed and keep mesh size down (rather than using SOLID186). How well this works I do not know, I have not gotten around to...

Check to see if the element is set for membrane behavior, might help. ____________ JohnyGluebag

PADT has posted several blurbs about solid-shell connections in there newsletter called 'The Focus': http://www.padtinc.com/epubs/focus/2008/0066_0804/TheFocus_66.pdf#Page=1 http://www.padtinc.com/epubs/focus/default.asp They use Ansys but you should be able to take something from it...

Apologies for not knowing or providing a reference, its late and I am not at work to check this. But, I was speaking with Ansys on this issue and was told that the default setting for linearized stress calcs on axisymmetric models does not satisfy ASME. However, a keyoption has been added that...

If you use Workbench, go tools-->solve process and set the number of cores. In Classic I think you can set this in one of the tabs in the product launcher window. This is all assuming you have the proper license to run more cores. Typical licenses let you grab two cores max. After that you...

Your first result does not make much sense to me. If you check your problem first by hand, with a free body diagram, your reaction force should be 2000N. So, you should expect a similar result from Ansys. Open the help file and read about 'mesh convergence'. There is a feature where you can...

Search the help file for 'point mass'. You can assign a mass to geometry and use accelerations to load the structure. Or you could ensure there is some sort of structure at the location of the CG so a point mass and a force could be assigned. ____________ JohnyGluebag

I am checking the strength of a new structure that has some fixed boundary conditions. The client wants me to pass on the reactions at these boundary conditions, so they can apply to there existing structure. Basically to see what my structure is doing to theres. In Simulation I go to...

cbrn, Aye, I was thinking along the same lines regarding the ram modules. Currently the quote is for 8x2GB ram, which will fill all the ram slots on the board. I have been pushing for 32GB but it seems like I am lucky to get 16GB. This will be a good first 'fast machine' that myself and the...

Thanks for the info. DDR3 was not offered for use with the HP AMD Opeteron setup, neither for the Dell Intel Xeon. qwicker, the machine I have gotten a quote for is nearly identical to yours. You have gone all out on the processors and ram, nice. The machine I am getting will be solving...

My boss wants me to spec out computer to run Ansys, allowed to spend $10k. I have most of it sorted out. We are not paying for the license to use more than 2 cores at this time, in the future this will happen though. Two things I cannot figure out: 1. So far no one at Dell or HP can confirm...

Good day, The new company I am working at just had some Ansys reps. stop by and give us a preview of Ansys11. I am a beginner to Ansys, been using Femap/Nastran for about a year now. So far my impression is that most people in my company prefer to work in classic and are not very impressed...

I forgot to mention, I did rename the scratch file to c:\scratch, but it did not fix the problem. If when I reinstall femap 8.1 and it works ok...I will have accept that it was just one of those things. Now I have a whole new set of stuff to figure out. How to couple acoustic elements and...

On a lark I installed femap 9.0. The company I am at is evaluating it for a possible upgrade. Femap 9.0 loaded a 6.7Gb op2 file no problem, and with good speed. I am loading results from a linear transient analysis. 1000 load sets. I then did some comparisons between importing the same...

Tomorrow I will give MSC a call again. I do not know much about the Nastran input, Femap is how I am setting everything up. In the past when I have had questions regarding Femap, MSC does not respond very well. Rightly so I guess, it would be better if I asked them questions about Patran. I...

Hello, I am having trouble with loading resutls into FEMAP8.1/MSC Nastran2001. I am trying to import a .op2 file about 1.7Gb in size. Every time I try I get an error when the scratch file reaches about 2.1Gb in size. Co-workers have been able to import .op2 files in excess of 3Gb...what am I...

The pieces are starting to come together. A consultant is supplying the physical testing data with load curves, numerical testing to compare too and such. After running a couple transient cases it is interesting to see how the model buckles differently than shown in the eigenvalue...

Thanks ThomasH. I am finding that there is no single resource to figure this out. I guess it would all be to easy then eh. JohnyGluebag.
