Re: Nonlinear solver computes deformation based on force loads
Hi Kevin, Thanks for your suggestions! I applied these modifications as you suggested. I first mesh the elastomer finer to 2x more nodes. Then I use tet10 and hexahedron elements. However, the results don't seem correct. I applied nodal force loads to surface points. For tet10 elements, some nodes h...

Re: Elmer does not flag when calculation is finished in multicore
Hi Lida,
I have a very similar requirement in my project. I use python to run the FEM problem. I attached my script below to execute and scan files. Hope they can be helpful. They are similar to PyElmer.

Nonlinear solver computes deformation based on force loads
Hi, the great Elmer team. I'm using Elmer to generate datasets for an elastomer deformation project. The elastomer is a thin cylinder (2cm rad with 0.3cm height). The top and lateral surfaces are fixed as our real-world setting, solid objects will contact the bottom surface and deform the elastomer....

Re: Disk deflection calculation
I see, so it mainly works as a boundary condition in this case. BTW, in order to save the computed U/DNU values at each node, what are the correct variable names to use in the SaveScalars solver? I referred to the solver manual and examples in the forum, but still confused about how the data saver w...

Re: Disk deflection calculation
Hi Mika and Kevin, Thanks for your illustrations. I think the difference here is the denominator. Mika suggests it should be the difference of displacement vectors, while Kevin thinks it's the difference between node positions. I'll double-check in the shell theory and reply here. Many thanks for yo...

Re: Disk deflection calculation
Hi Kevin, Thanks for the links. I went through git test files, forum posts, and Chap. 8 of the Elmer Models Manual. I understand U represents the displacement of the mid-plane nodes in XYZ directions. However, I'm still confused about the meaning of DNU. Could you kindly explain DNU using the below ...

Re: Disk deflection calculation
Hi Mika, Thanks for your fast reply and your illustrations regarding the Smitc solver. It makes sense that the plate solver only considers the stretch effect and I've switched to the shell solver as you suggested. Since I'm not very familiar with these techniques and there is no example of the shell...

Re: Disk deflection
Hi Elmer team, Thanks for your fast reply! To create an internal boundary, I referred to this post http://www.elmerfem.org/forum/viewtopic.php?t=43 . Specifically, I created a boundary condition specifying deflection on a node, as below. Boundary Condition 2 Target Coordinates(1,2) = Real 0.005 0.00...

Disk deflection
Hi, I'm a newbie to FEM and Elmer, fascinated by the clean and powerful solver. I'm working on simulating the deformation of a disk under certain force fields. Currently, I followed tutorial 9 on the ElmerGUI tutorials to obtain the deflection of a linear plate. I successfully modify the plate shape...
