Re: LDA, Only one core used?
Some useful info here http://communities.ptc.com/message/266735#266735 For single core processes such as LDA get the fastest single core cpu possible. Regards

We have implemented a ramdisk via IMdisk on the same computer and it increased the speed by 5 fold! 10 minute iterations are now only taking 2 minutes! Amazing! However the CPU load only increased from...

Hi Jonathan, Glad to hear the RAM disk solution helped! However, I suspect that the remaining 'bottleneck' is that you have three out of four cores sitting mostly idle; as discussed at the beginning of...

Hello, I think my challenge is within the range of this topic. I have a structure which is in force balance, well suited for linear FEA either by manual 3 point constraint or by inertia relief. However...

A quick question: what are your elapsed time and CPU time from an analysis, using the RAM disk? Is CPU time now roughly equal to elapsed time?
View ArticleRe: LDA, Only one core used?
I have recently moved to an i7 machine with 32 GB of RAM abd the speed doubled again. There are times when the CPU is opperating at 100% on all cores, but most of the time (as you mentioned with LDA)...

Antonius, thanks for the reply, but its not a motion analysis. I am trying to get average slippage factors for contact regions for the increasing loads at each time step.

Does anyone have any experience from standards like ASME or similar, etc where linearized stress results are used for dimensioning? I have no problem understanding the linearized stress query, but how...

Denis, Si les déplacements sont petits, une distribution uniforme est OK. Ca dépend aussi de la rigidité du poids.Sinon tu peux faire une analyse contact, peut-être mème avec "déplacements large" pour...

Re: Rigid load
It depends on what you think the real system behaviour will be. If you think the beam will not bend at all where the load is, you could use a rigid link on the load contact surface to prevent that...

Rigid Body Analysis - 3D Bolt Pattern
Does anybody have a 3D bolt pattern analysis already programed in Excel? This is a spreadsheet where the reaction loads are calculated at all the points. I have included a screenshot for...

I would typically run the analysis, go to results, and then create a graph displaying a measure vs. time. Then click "File-export-excel". /Mats L/

Re: Compiled Measures Data at Each Time Step
Hi Beau You need to define user defined output intervals, in my example the .res file contains all values for all meaures in all requested output intervals for both pass1 and pass2.Succes! Erik

Hi Victor In your example, I would try my utmost to provide some area to the point where you wish to constrain.Make a small spherical cavity, a datum point at the center and a weighted link.In that way...

Mats,Thanks for the respsonse. This way will work, but if I have 40 contact areas and 6 load cases, it will take a while to compile the results. So I was hoping there would be a file (.res) that...

Erik,I was hopeful that using more time steps I would get the output I was looking for as you have said. I have tried this in the past, but gave it another shot this morning. It seems that I only get...
