Update - with regard to my second last line in my post above: I have recently found that Mecway will handle beam elements for NL large strain.

Hi I would recommend Mecway. Mecway certainly is a spinoff of Lisa but more advanced. They have a great forum. Victor (the Main Software guy I think) responds quickly and is very very helpful. I started with Lisa and then discovered Mecway. Amazingly, the Lisa guys gave me my money back...

One Point, The tensor stresses x,y and z match the Algors GUI axes. I'll refer to the axes on Algor's GUI: Lets assume you have set your model up so the axis of your pipe is z, x direction is in the radial direction (90 deg to the axis of your pipe). This means y direction is also at 90 deg...

Greetings, 1. Does any one know how I can draw in a long series of plate elements which represent the weld, on a midplane meshed structure (or brick element structure) which I have imported from Inventor? 2. Has anyone had much experience simulating welds using ASM? 3. Can anyone comment...

EngAddict, Thanks again for this. I'm still on a steep curve with ASM! I'll try the delete face/heal option as well as some of your other suggestions-thanks. I finally found fusion to be reasonably ok at deleting fillets but it took me a while - it's still a bit clunky. I'll need to look at...

EngAddict, Thanks for your previous post. I starting to use ASM for a large assembly consisting of beams, plates etc. I've spent some time using fusion to delete fillets and also using the Inventor "simplify model" tool within Inventor. I have had trouble finding an easy way to delete...

Greetings, 1. I've been trying to do a shrink fit between a simple cylindrical steel hub (OD = 216 mm)and a solid round steel shaft (dia 140 mm) (using ASM). 2. I've been using solid brick elements for both parts. 3. I draw the parts assembled in inventor with zero mm radial interference 4. I...

ChiraL, No, I'm sorry. I have only just started using ASM and have no history with Algor. Perhaps some of the Algor users could comment or possibly contact Autodesk themselves. I believe many of the Algor crew are still there. Cheers

EngAddict, I note your interest in Calculix. I have not persevered for long with Calculix. My first impression was that it needed a good interface so that I could import cad geometry. I tried to bring in files from Inventor. I found the process difficult and gave up. I was hoping to use...

EngAddict, Thanks so much for your reply. It confirms my impressions from other sources. It looks like we are going ahead with ASM in the near future. This is largely driven by the useability factor with Inventor. We mainly use Inventor and are expecting to find the interoperability with ASM...

4Pipes, Thankyou for this. It has been very helpful. We value the feedback. Regards from Western Australia

Greetings, Could any one give me their opinions on the use of Autodesk Simulation Mechanical (ASM) for the strength and fatigue analysis of welded or bolted steel plate structures? Our draftspersons use Inventor exclusively so ASM is an obvious choice however, we are also considering NX Nastran...

EngAddict, thanks, those links are very helpful, I need to read them more thoroughly and look for a more capable fea application.

Engaddict, thanks for your post. Re part4. I need to look at the strength of the weld i.e. I need to look at the fatigue life and strength of welded structures. Many times, the weld area is highly stressed so I need to accurately model the weld itself as well as use appropriate contact...

Thanks Greg, I was starting to think that.

HI, I am using Inventor 2011 for FEA of welded structures. Generally it is ok unless I am interested in the stresses in the weld. I get a lot of stress singularities here. I also have a number of issues when I try to model a flange that has been welded around its outside to another member or...
