Re: Error in `ElmerSolver': free(): invalid next size

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 :-( :-D

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

Sincerely
Maike

Re: Error in `ElmerSolver': free(): invalid next size

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!

Sincerely
Maike

Re: Error in `ElmerSolver': free(): invalid next size

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...

Re: Error in `ElmerSolver': free(): invalid next size

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,
Maike

Re: Error in `ElmerSolver': free(): invalid next size

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 ...

Re: Error in `ElmerSolver': free(): invalid next size

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 ***

Re: Error in `ElmerSolver': free(): invalid next size

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.

Re: Error in `ElmerSolver': free(): invalid next size

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.

Re: Error in `ElmerSolver': free(): invalid next size

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.

Error in `ElmerSolver': free(): invalid next size

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.
