thanks very much, the /3Gb switch worked really well. nastran handles a 1.5 mil DOF analysis no problem. very nice!

Hi, i am receiving a S1111: insufficient Virtual Memory Failure. i have read thread825-135347 and have followed the steps suggested by dcmacs: 1. Set DECOMPMETHOD to the PCGLSS solver. 2. Set SPARSEITERMODE to 3. This uses the least memory and but you may not get SPC forces, not sure. 3...

also, i work on relitively large forged part aluminum weldments (bicycle frames) and in metric, they are over 1000mm (units). will NE Nastran have an issue scaling up this big because my model size exceeds the +/-500unit Parasonlid boundary? thanks, darcyo

Hi all, i started a similar thread to this with regards to scailing, however, i am now having isuses with importing pro/e assembly, and then scaling up to metric within NE Nastran. not only do i lose my naming conventions from the import (due to having to scale up by 25.4 and a new set of solids...

thanks guys. so Nastran then uses Standard International (S.I.) and standard Imperial units then? because, SI units are N m s, not N mm s.. guess that is because 1MPa is 1N/mm^2... so is there a reference page that either of you know of with Nastran's system of units? much appreciated, darcyo

Hi there. i am new to Nastran, and i am importing large assemblies from Pro/E, using iges format (the parasolid woudl not import), and i have been successful creating meshes, applying contact surfs, etc. i would like to be working in mm\N\s\Kg (metric). i am using 72e9 for E of AL7005. my stress...

hey, yeah, this is kinda huge. sorry to dissapoint, but i found out what the problem is... search_path_file... when i point to search_path locations over the network, my mechanism is slow and choppy, when i change the contents of search_path_file to only point to directories that are local, my...

Hello, I would like to know if anyone out there is having similar issues to me with regards to slow mechanisms in Wildfire 2.0. More specifically, I am on M030 and am running a mechanized motion using drivers. the driven motion of the assembly is extremely slow and choppy ONLY when i have parts...

yeah, I am on wildfire... I have thought about getting the advanced Mechanism package going, though it lacks some features that motion has: bearing loads and the ability to import loads from motion into structure.

hi there, i was just wondering if anyone out there has any working experience with cold forming Al7005 plate. I am worried about lamellar tearing while bending in the annealed state. Any suggested heat treatments prior to forming/bending? can it be done? Maybe i can substitute 7005 with a silica...

I just wanted to know if anyone out there has figured out how to use Borland C++ Builder 6 to compile mechanica motion studies. see, the problem is, is that the Borland compiler costs $130 CAD and the only supported compiler (Microsoft Visual C++) comes only as a C++ designing suite and costs...

I also heard that wildfire 2 has a new licensing method: now licneses can be "borrowed" from the license server - allowing a pro/e user, for example, to borrow a license on his/her laptop and take it home with them (while disconnected from the network). pretty sweet. anybody used this licensing...

Peter, Pro/M is well suited for truss simulations. Pro/M uses high order beam elements whose shape functions more accurately predict strains than linear elements of many simple FEA packages. To be honest however, the accuracy of all top-competing FEA packages are quite similar, as the FE solvers...

i checked all of the configs, and i really don't think there is a way to do it.

from my experience with multi-opjective design studies, the only options to filter (or derive) the database are to: 1. keep goal between min and max values 2. using pareto filter, to obtain the max, or min for the populated database. as far as a normal distribution, i am assuming that you mean...

i'm assuming you are in pro/detail... Query select it by clicking on it, then right click until you get it. the right click again and goto properties.

wow! somehow i knew that this question would spark a high-quality debate, one which is very similar to the one that i have experienced here at work. as with everything in life, there are advantages and disadvantages to everything. infact, this is the real basis of engineering design in itself -...

groover, I have absolutely no practical experience with this sort of thing - though i think that electronic components are typically welded using ultrasonic welding. You can follow this link as a starting point: http://www.staplaultrasonics.com/appl/frame.htm hope this helps.

Vinod, what condition is the wire in? was the wire ever exposed to moisture? is the oil coated? are you using the proper contact tube (proper internal diameter) for the wire? have you measured the wire diameter? anyway, the point of these questions is to determine if there is any...

additions such as thorium (up to 2wt%) and Zirconium change the thermionic emisivity of the electrode - which is essentially the amount of charge required to strip an electrode from the electrode surface. the addition of thorium allows for easier electrode stripping and thus reduces electrode...
