  in deflection of plate on elastic support (zigzag?) Comment by J_Marc August 2015
• Hi, This is in regards to the original plate over elastic foundation post. I have attached a 2m square plate with 1m square centre surface load of 80te. I was just curious about the problem above. Everything was good "von mises stress" etc had a sym…

  in Does Mecway have the ability to apply a ramp force? Comment by J_Marc August 2015
• Hi prop_design, There is a fair amount of lag with 2.3 million node and it is not workable in my opinion. 500,000 nodes with 16Gb Z420 is okay if you don't mind running the solver overnight. In my case this was an accident because I didn't set the c…

  in How many nodes can you work with? Comment by J_Marc July 2015
• Hi prop_design, Using netgen I generated a monster 2.3 million nodes on my first attempt from a 3D cad import (it was left overnight on a 16GB Z420 workstation). I was able to load it into Mecway view and rotate around. Unfortunately this model had…

• Victor, VMH & Prop_Design, I read through all the post and watched the video. I have learned thanks to you a better way to model this problem on Mecway (yes, these holes were meant to be circular not hexagonal). I am very grateful for the time …

  in How to model a pin inside a link plate? Comment by J_Marc July 2015
• Hi prop_design, Yes, I installed python 3.5 the latest release but this version of Netgen likes python version 3.4. Thanks for the heads up. I didn't do a CAD model for the link plate. I created it in Mecway. As for the Liml file, they are uploaded …

• Hi Prop_design, It's unfortunate but Netgen gives me an error after install. I am still experimenting with Mecway and I like it so far.

• Very true, I forgot to include the stress concentration factor Kt 2.16 Nominal tension stress σnom 416.67 MPa Maximum tension stress at the edge of hole σmax 898.28 MPa

• Hi, Yes I was more after the stress at the hole. I get 808.6MPa on the coarse; 500e3N/(120mm-60mm)x20mm =416.7MPa I will try refining the mesh with hex8 & hex20. PS : Where do I get Netgen, Thank for your help.

• Hi, I have been experimenting. The closest I got to a consistent result was by converting the 500kN +Y force as a pressure of 265.3MPa normal to the arch surface. Superfine meshed the entire part to 10240 elements and 12663 nodes.

• Hi Victor, Thanks for the prompt response, I have attached two liml file. Coarse & Refine 3D model of the plate in question. I was expecting the stress to be around 416MPa.

  in Mecway on Mac OSX using VirtualBox Comment by J_Marc June 2015
• Hi Victor, I attached the graphiclogs.txt which did spit out a lot of errors. I believe you are right. I tried the above fix by turning on 2D & 3D graphics from the settings but it spits out another error: "Failed to open a session for the virt…
