ok, so I tried again with the parameter set to 1000 GB and it finished without error but of course again no faster. The sky is the limit.

@cwharpe for IIW I need stress information at very specific Locations depending in mesh size and If I want to pic nodes I would have a have nodes at these specific locations which would be a pain when meshing. With the interpolated plot/table it w…
-
The solver finished with the parameter beeing set to 190 but it was no quicker compared to the parameter being set to 100GB So it seems that it does not hurt to set it as high as you like as long as you stay below the installed RAM.

Hi @Victor, the components that are needed for weld assessment accornding to FKM "Analytical Strength Assessment" are: Stress normal to weld Stress parallel to weld shear stress normal to weld shear stess parallel to weld as shown in this image: …
-
The good thing when the solver fails is that I dont have to wait too long. Setting the Parameter to 200 caused the P-9 error (the machine has 192 GB RAM) and the parameter has again be reset to zero. Ill try 190 GB next, so just below installed RAM.
-
If the parameter is set to a value greater than the available RAM, I get P-9 error shortly after the solving matrix phase beginns (so seting it to infinity by default may not be a good idea). I had the parameter set to 1000 GB which is above the cap…
-
Setting the value to 160 GB gave me no further improvements. Solving time is nearly identical compared to the parameter beeing set to 100 GB. I'll try setting a value that is higher than the available RAM and see what happens.
-
Setting the parameter to 100 GB makes the entire Solutuon about 45% faster compared to the parameter beeing set to 20 GB which is mainly due to the solving mateix phase that goes down from approx. 6h 15 min to 3h 30 min. Rocketship.... …

Parameter set to 100 GB:

I assume the diagram would show membrane, membrane+ bending and peak stress for all the stress components in SCL coordinate system? It would be convinient to have mm on the x-axis and in the table in addition to the points 1 to 99 like in the scre…

Seems to work with above value set to 20 GB on the Workstation: Allocation phase and assembling Phase also seem quite a bit quicker in V20 compared to V20Beta. Dont know if due the above parameter (20GB) or due to the solve improvements. trying …
-
OK, thank you, that sounds promising. I'll let you know if I can make out any improvements.
-
OK, i'll just try it out when I get the chance and let you know. The Laptop hast 64 GB by the way so it should have enough RAM available to use or try to exeed the specified value of 14.4 GB.
-
Thanks for the new Verseion @Victor ! Has the internal solver become faster even compared to mecway200_Beta3?
-
Hi @Victor to be honest I don't quite understand what you mean. You are suggesting that reducing the value in Mecway with the labs option might help although the P-9 error is caused if it is set too low. If the Workstation may wants to use more tha…
-
Now the Laptop also solved a model with ~1.5 Mio nodes and many bonded contacts. Could it be a hardware related problem? Laptop: Workstation The workstation does have two different RAM installed. But the issue we have now has already been t…
-
Appearantly it seems to be an issue with the work station. The same model that solves on the laptop will not solve on the workstation for some reason. It gets the P-9 error shortly after the "solving matrix" phase begins.
-
We are using the internal solver. CCX is not an option for some reasons. So I assume Pastix / Pardiso does not apply? I did solve a simple model with more than two million nodes in the meantime on my laptop. @Victor ,any idea what could be the…
-
sorry, bad quality, but maybe helpful nonetheless. approx. 1.500.000 nodes in the model.

Hello @Victor and @Andrea , first, I found this article explaining the differnt methods for evaluation hot spot stress. It is in german originally, but google translator does an ok job, exept that it confuses stress with voltage (same word in germa…
-
Hi @Victor , I tried your suggestion and it worked as you described. Note that the beam resembling the bolt must consist of at least two elements so that it has a central node (to show the bolt forces) that is not shared with the the spider beams …
-
@Andrea is right, sorry for the insudficient information in my last post. I'll try to put together some more comprehensive information tomorrow which I have available only in german so I have to translate it first.
-
Thanks @Victor, another valuable addition! A couple of weeks ago I promised to dig out a an illustration showcasing the stress components that I would be interested in in order to use the stressliarization tool in Mecway for weld analysis: Or, a…
-
Hi @Sergio , Thanks for the Insight! Do you have a workflow for changing the thickness of the part when the shells are already expanded to solids?
-
Hi @Victor, That is a very convinient feature! I sent you a mail with the outline tree.
-
I would like that, too. Another nice improvment for the mesh tools could be to add something like scale tool that scales solid element normal to their surface (similar to an offset in CAD software ) Our use case is sheet metal parts. At some …
-
No, no time steps. I tried again and gave it more time. This time it worked. Don't know why its taking so long in this model (600k nodes). Maybe because of several configurations? Sorry, I can't share the model. Can the sum be defined before solvin…
-
For a small test model it worked just like you intended. On a large model the curser kept spinning (as in the software is working on something) and I shut mecway down after waiting about 10 min coz I thought there was someting wrong.
-
This Button: It is not there in V19. I thought it was intended to save the sum in outline tree or something like that...
-
@Victor , I just noticed that with beta version clickin on the "ok" botton causes Mecway to get stuck. Back to the always visible model outlines: They do get in the way quite a bit if there are many components in one model. So having an option …
