Sorry for delayed response, I'm tied up with getting a report done but will send something as soon as I get a chance.

The latest version of the full simulation has run, mostly. It did something curious that I'll go through here if anyone is interested. And appears to be another interesting aspect of using automatic time stepping. It had been running overnight and …

Since it works at low speed, I'd ramp the speed - eg. enter it as "123 * t" instead of "123". Then you should see the solution up to the point of failure, if any. My 'full' simulation had the loads defined with tables, which included some ramping …
-
Turning off quasi static causes loads to be ramped automatically, so the sudden application of full load might be the problem. It looks like it might be working now, and if it does solve (still running) then it would appear to be related to time s…

¿Have you check there is no rigid body rotation?. Whilst that is my favourite mistake I've avoided it this time! Always worth checking, and worth checking that I checked. ¿Are you able to load partial solution during the analysis? If yes, ¿How doe…

Contour plot values slightly outside the specified range were being colored as inside the range. This error is reduced but still present. (version 19.0) That seems to have dealt with the problems I was having, thank you. I appreciate that you indi…

prop_design 4:45PM Not sure if this is what you are experiencing. However, a long time ago, I noticed Netgen yields different meshes based on where the part is located. I brought this up to Victor. As far as I know, that bug still exists. I think…
-
It looks like I'd made the same error in both cases but that the error caused different results, or at least the results I looked at were different. And understandably so. I had failed to put a constraint in to eliminate the rotational degree of fr…

disla 1:32PM The Center of mass was a nice check ...Additionally: -Same Density/Mass? -Same Orientation in 3D Space? I would perform a fast Modal vibration analysis to see if they both agree. Request 12 modes and pay attention also to the first si…

JohnM 12:34PM That does sound a little strange. I would expect the meshes to be identical, but does the offset affect that somehow? Are the messages identical? I hadn't thought to look. There is a difference in the quantities, but not a great deal…

I was looking at the custom CCS cards with a view to simplifying the model before expanding it until a full 3D, I was thinking of reducing the number of elements but was concerned that that might cause problems. I used "Rotate/copy..." to create a …

Hi, I do a lot of work with axisymmetric geometry and generally use the thin sector and frictionless support (or similar) technique so have a lot of interest in whether this is producing valid results. I'm struggling to understand how there could be…
-
Oops, I'd missed your reply. This means I can cross replicating the problem off my to do list. There's no great urgency as far as I'm concerned now that I've got a work-around. Thanks for looking into this and working on it.
-
Hi, Thanks for taking a look at this. Sorry for not replying sooner. WRT high vs low resolution - I've just tried increasing the resolution, with no visible difference on the affected area. If I click on each visible node for an element then I can…
-
Hi, I stumbled across this topic because I'm trying to understand how to design parts made out of brittle materials. In my research I've found quite a few papers and having found this topic I'll post some links to see if they help anyone here. For t…
-
Hi JohnM, Thanks for taking a look at this, and your example. It was particularly useful because I'd made some kind of mistake in my simplified model and I was pulling my hair out thinking I'd completely misunderstood how it worked. I've run throu…
-
Hi JohnM, Sorry for delay in replying. You're right and that's what I had been doing but I found that I was struggling to keep my records straight as to what geometry had been run in what analysis. What Sergio suggested is basically the same as you'…
-
This afternoon I've been editting the .liml file as per Sergio's suggestion and it has worked well so far. The surface definitions have all re-attached correctly, materials already assigned and the loads and constraints applied as required. Thanks f…
-
Hi, I might be too late to help with this but I stumbled across this post because I'd been having some issues with cylindrical coordinates. I realised that I'd aligned things differently to how the DisplacementCylindrical.liml and StressCylindrical.…
-
Hi, I'm currently working with a similarly axisymmetric item in 3D and using this process, which seems to work well but I do have a question... Is there a way to replace the geometry rather than reload it? What I mean is that I'd like the name in th…
-
Hi, An alternative way to generate a surface mesh would be to generate a surface in SolidWorks and export that as a STEP file. I didn't realise you could do that until it was pointed out to me here and it seems to work well. But... as Victor says th…
-
Sergio, thanks for the tip about surfaces. I don't use very often, probably never! so I wouldn't have thought of it.
-
I've not had access to the forum for a couple of days so am catching up. Thank you for your comments. I ran the internal solver again and left it. After several hours it did solve the model that PARDISO solved (but didn't show results for). I then t…
-
I did make some progress over the weekend since my original post. I got a much better looking mesh by using gmsh through Mecway. I'd previously tried using gmsh completely stand-alone, and then import the mesh in Mecway but I'd made mistakes in the …
-
Hi Sergio, Thanks for taking a look at this. I'm deliberately not using an axisymmetric model because I think that making that approximation would lose the details that I'm concerned with, i.e. in the thread. I'm sure you can imagine that an axisymm…
