ElmerGrid 8 2 .unv -autoclean

Hi all, Been having issues using ElmerGrid 8 2. I recieve the following using Windows command prompt. C:\Program Files (x86)\Elmer 8.3-432ee0dd\bin>ElmerGrid 8 2 test.unv -autoclean Starting program Elmergrid Elmergrid reading in-line arguments Lower dimensional boundaries will be removed Materials ...

Re: Elmer Challenge

Kevin Thank you. I was under the impression that the groups had to be defined within the geometry as well as the mesh. Such a simple method but I'm still running into issues with Elmer recognizing the groups when I load the .unv file I created based on your example. Attempted the ElmerGrid 8 2 comma...

Re: Elmer Challenge

Plenty of trial and error with Salome. I probably went about it in a round about way but I think I was able to create somewhat of the mesh that I was looking for.

Re: Elmer Challenge

Kevin I'm guessing your able to define the internal row of elements as a separate body within the mesh rather than defining these areas as faces within the geometry? I've got a small amount of experience with Salome. I initially started out using Salome at the beginning stages of the project to crea...

Re: Elmer Challenge

Kevin,

In regards to the examples you posted, (internal edge element addition and internal row of elements as a separate body) how did you go about manipulating the original mesh to include these additions? Did you use a mesh generation software or are these additions possible in Elmer?

Re: Elmer Challenge

I'm going to piggyback on the initial post. Another portion of the project involves replicating deflection data for 4-point bending and ring on ring testing using FEM analysis. I'm brainstorming how to create the mesh in order to apply boundary constraints for use with the shell solver. Thus far my ...

Kevin

Wow, well done! I spent quite a bit of time trying to learn the script for the shell solver but there were still some areas of confusion for myself, an Elmer beginner. This will definitely help connect the dots.

Re: Elmer Challenge

Mika, Thank you! I'm trying my best to understand and recreate your sif file. Again, I'm completely new to Elmer. All the work I've been able to accomplish thus far is mainly based off tutorials and I'm having a difficult time finding tutorials regarding the shell solver. When I started working with...

Re: Elmer Challenge

Greatly appreciate the replies. Lots of great information to consider. We ran into similar issues with the SMITC solver and have since focused on the nonlinear elasticity equation set. Also making attempts at manipulating the mesh size and volume in order to recreate the E1300 deflection values. Clo...
