Elmer Discussion Forum

Hi Peter,

this project has been put on hold and I now have to work on other projects. And despite of the situation I still have to go to work

So it would be nice if you'd find the time but there is no rush.

Sincerely

Hi Peter,

thank you for your answer. Unfortunately I don't think I will find the time to get into coding.

But if someday somebody manages to make the projector work for contact I'd be happy to get back to Elmer!

Hi Kevin, thank you for your effort and time. I got my case running by re-meshing and slightly altering the parameters in Salome (e.g. max element size 0.031 instead of 0.03). Which was tiring, because sometimes I had to re-mesh 10 times until it finally worked. I also did biaxial tensile tests, whe...

Hi Peter,

i would be very thankful if you could inform me about any new developments in the contact mechanics area, especially concerning projectors that would be more suitable for my problem.

Sincerely,

Hello Peter, thank you for your answer and effort. I am a little confused now, because the exact same case works using this mesh for example: https://www.dropbox.com/s/8inxaiv10bgkh20/mesh.zip?dl=0 This is the same geometry just with a coarser mesh. It actually delivers pretty good results close to ...

After remeshing a thousand times it acutally ran through until Elasticity iteration 10 and almost made it through the first timestep. But then again crashed, this time with the error:

*** Error in `ElmerSolver': double free or corruption (!prev): 0x00000000034d9a00 ***

It's also not always the same error. Sometimes I also get

*** Error in `ElmerSolver': corrupted size vs. prev_size: 0x0000000002893b10 ***

This is also pointer related.

It has something to do with a pointer error. I think the Solver wants to free something it didn't allocate. This is not an error thrown by ElmerSolver, but by the system itself.

I checked that via the "top" command in a terminal. I did not run out of RAM. I have a 80 GB machine with 20 GB Swap and the Swap wasn't even used. I already ran bigger simulations with more nodes.

Hello everyone, I keep on getting this Error: *** Error in `ElmerSolver': free(): invalid next size (fast): 0x0000000003ed8970 *** I remeshed my geometry with different parameters about twenty times now and it keeps on failing in the second elasticity iteration. I did the exact same simulation on th...
